Fig. 3 is referred to, is a kind of flow diagram of communication means based on parameter negotiation provided in an embodiment of the present invention, Specifically, as shown in figure 3, the embodiment of the present invention the method may include following steps：

S101：First communication equipment holds consultation to target component according to default negotiation algorithm, and after obtaining the negotiation Obtained targeted parameter value, wherein the corresponding channel bit error rate of the targeted parameter value is less than default bit error rate threshold.

It should be noted that the method for the embodiment of the present invention can be applied particularly in digital communication system, and can have Body executes in the first communication equipment in the digital communication system, wherein first communication equipment is transmitter or receiver.

In specific embodiment, a bit error rate threshold can be predefined according to actual demand.For example, when due to link negotiation Between it is shorter, adaptive equalization technique generally using be higher than code requirement, such as current code requirement channel bit error rate be 10^- ¹²Bit/s (bits per second), then can according to higher than this 10^-12The channel bit error rate of bit/s such as 10^-7Ginsengs of the bit/s to communication equipment Number is held consultation.

Specifically, when default negotiation algorithm holds consultation to target component, the first communication equipment can first add in positive adjustment Weight parameter, if the bit error rate becomes larger, otherwise reversed adjusting parameter continues positive adjusting parameter, is less than 10 until working as the bit error rate^- ⁷When bit/s, targeted parameter value (after negotiating) after the first communication equipment can acquire the adjustment.

S102：First communication equipment judge the targeted parameter value whether in preset with the target component pair Within the scope of the parameter region answered.

In specific embodiment, since the transmitter parameter and receiver parameters negotiated every time are more concentrated, built based on the parameter Vertical link is more stable, and the reliability for eliminating ISI is also higher.Therefore, can be that target component configures to obtain a parameter region in advance Domain, the parameter region indicate the target component of preferable value range, such as the intermediate region pair that parameter distribution is more concentrated in Fig. 1 The parameter value answered.

Optionally, which can be the insertion according to the transmission channel between the transmitter and receiver detected Loss (Insert Loss, referred to as " IL ") information determines.Then first communication equipment can also be led to by obtaining with described second Believe the insertion loss information of the transmission channel between equipment, thus using the insertion loss information of acquisition as foundation, preset To parameter region corresponding with the target component.

Further alternative, which can be determined according to the operating temperature under the network working environment detected 's.Then first communication equipment can also by obtaining the operating temperature under working environment residing for first communication equipment, and with The corresponding temperature range of the operating temperature got is foundation, preset to obtain parameter region corresponding with the target component Domain.

After the targeted parameter value after acquiring the negotiation, you can detect the value for the target component that the negotiation obtains i.e. Whether targeted parameter value is within the scope of the corresponding parameter region of the target component.If within the scope of the parameter region, that is, sentence Disconnected result is when being, to negotiate to terminate, and can perform step S103；Otherwise, step S101 is can perform, the negotiation is repeated Journey, until the new targeted parameter value negotiated is within the scope of the parameter region.

S103：If within the scope of the parameter region, first communication equipment be based on the targeted parameter value with Second communication equipment establishes communication link, and is communicated with second communication equipment by the communication link.

In specific embodiment, negotiating to obtain the target component within the scope of the corresponding parameter region of the target component When value, i.e. preferable parameter value, you can establish link by the targeted parameter value negotiated and the second communication equipment, and being based on should The link of foundation is communicated, and to overcome intersymbol interference, and promotes the stability of communication link.Wherein, which sets It is standby corresponding with the current progress equipment of parameter negotiation, if that is, the first communication equipment for currently carrying out parameter negotiation is number Transmitter in communication system, i.e. second communication equipment are the receiver in the digital communication system；It is corresponding, if when advancing First communication equipment of row parameter negotiation is the receiver in digital communication system, i.e., second communication equipment is the digital communication Transmitter in system.

It is further alternative, in first communication equipment it is held consultation to target component according to default negotiation algorithm Before, first communication equipment also can detect the enabled current state of preset negotiation, and the current state includes open state Or closed state；If described negotiate to enable to be in open state, first communication equipment executes described according to default negotiation Algorithm holds consultation to target component, and the step of obtaining the targeted parameter value obtained after the negotiation；If described negotiate to enable It is closed, then first communication equipment obtains preset parameter setting values corresponding with the target component, and will The parameter setting values are as targeted parameter value.That is, it can be pre-configured with the enabled switch of a negotiation parameter, and it is preset One parameter setting values corresponding with the target component, to open the enabled switch, i.e., negotiation is enabled is in open state When, the triggering of the first communication equipment carries out parameter negotiation according to preset negotiation algorithm and obtains the flow of targeted parameter value；Otherwise, Then first communication equipment directly invokes that this is preset with the parameter setting values, and using the parameter setting values as the target component Value, is communicated with being based on the targeted parameter value i.e. parameter setting values with the second communication equipment.

Further, it may includes multiple to need the parameter negotiated, then it is pre- to may respectively be the parameter that each needs is negotiated A parameter region is set, parameter negotiation is carried out to be based on each corresponding parameter region.Specifically, each can be needed to assist The parameter of quotient holds consultation to the target component respectively as target component, according to default negotiation algorithm, after obtaining the negotiation Obtained targeted parameter value, and judge whether the targeted parameter value is in preset parameter region corresponding with the target component Within the scope of domain；It is within the scope of corresponding parameter region when the target component that multiple needs are negotiated corresponds to targeted parameter value When, then first communication equipment can be led to based on multiple targeted parameter values and second within the scope of corresponding parameter region Letter equipment establishes communication link, and is communicated with second communication equipment by the communication link.Wherein, if this first Communication equipment is transmitter, then the parameter held consultation is needed to may include the postemphasising and (be generally denoted as C1) of transmitter, amplitude (one As be denoted as C0), the parameters such as preshoot (being generally denoted as C3)；If first communication equipment is receiver, the ginseng held consultation is needed Number may include the gains (being generally denoted as GAIN) of receiver, penalty coefficient (ADC), linear feedback parameter (be generally denoted as DFE0, DFE1 etc.) etc. parameters.Optionally, which can be the fixation algorithm for being solidificated in inside communication equipment, can also It is the negotiation algorithm for holding consultation within the scope of the parameter region generated according to the parameter region of the setting.

It is further alternative, when the targeted parameter value is not within the scope of the parameter region, first communication Equipment is controllable repeat it is described hold consultation to target component according to default negotiation algorithm, and obtained after obtaining the negotiation Targeted parameter value, and judge the targeted parameter value whether be in preset parameter region corresponding with the target component Step in range repeats step S101 to S102；And record the negotiation number of the negotiation；First communication is set Whether the negotiation number of standby detection record is more than given threshold；If being more than the given threshold, first communication is set Preparation goes out alarm.Wherein, which can pre-set to obtain, for example be set as 5 times, then the first communication equipment can be in repetition Alerted after 5 subparameters are negotiated, in order to notify its exception of relevant device.

In embodiments of the present invention, it can hold consultation, assist according to the target component that preset negotiation algorithm negotiates needs Quotient obtains the targeted parameter value that channel bit error rate is less than default bit error rate threshold, and the target component obtained by detecting the negotiation Whether value is in preset parameter region corresponding with the target component, and the parameter region range is in the targeted parameter value It is determined when interior and negotiates to complete, led to establishing communication link with the second communication equipment based on the targeted parameter value negotiated Letter, so as to effectively overcome the intersymbol interference brought due to influences such as fading channels so that enhance the stabilization of communication link Property, and improve system reliability.

Fig. 4 is referred to, is a kind of structural schematic diagram of communication system based on parameter negotiation provided in an embodiment of the present invention, Specifically, as shown in figure 4, the system of the embodiment of the present invention may include：Transmitter 1 and receiver 2；Wherein,

The transmitter 1 for holding consultation to first object parameter according to preset first negotiation algorithm, and obtains institute State the first object parameter value obtained after negotiating；Judge the first object parameter value whether in preset with first mesh It marks within the scope of the corresponding parameter region of parameter；If within the scope of the corresponding parameter region of the first object parameter；Notice institute Receiver 2 is stated to hold consultation according to preset the second target component of second negotiation algorithm pair；

The receiver 2 for holding consultation according to preset the second target component of second negotiation algorithm pair, and obtains institute State the second targeted parameter value obtained after negotiating；Judge second targeted parameter value whether in preset with second mesh It marks within the scope of the corresponding parameter region of parameter；If within the scope of the corresponding parameter region of second target component, it is based on The first object parameter value establishes communication link with second target component with the transmitter 1, and passes through the communication Link is communicated with the transmitter 1；Wherein, the corresponding channel bit error rate of the first object parameter value is less than default error code Rate threshold value, and the corresponding channel bit error rate of second targeted parameter value is less than default bit error rate threshold.

Since negotiation algorithm is generally solidificated in chip interior, in design on board level, negotiate to calculate if system can not change it Method, then in parameter-negotiation procedure, the targeted parameter value that system grabs negotiate, and judge that the targeted parameter value negotiated is It is no to fall into the parameter region of setting.If dropped into the parameter region of setting, negotiate to complete；Otherwise channel is triggered again Parameter negotiation is carried out, the parameter region of the setting is fallen into until negotiating parameter.Wherein, the parameter region set as it is preset with The corresponding parameter region of target component.

Optionally, the parameter region corresponding with the first object parameter and/or second target component are corresponding Parameter region can be according to the insertion loss information of the transmission channel between the transmitter 1 and the receiver 2 determine Go out.

Further alternative, the corresponding parameter region of the first object parameter can also be according to 1 institute of the transmitter What the operating temperature range under place's working environment was determined；Second target component corresponds to parameter region and can also be according to institute State what the operating temperature range under working environment residing for receiver 2 was determined.

Emulation or actual test are carried out to transmission channel specifically, can first pass through in advance, obtain transmitter and receiver it Between transmission channel insertion loss (IL) information such as insertion loss value, to the preset transmission for obtaining that transmitting can be met Machine, receiver parameters region.Optionally, operating temperature range when can also work further combined with the transmitter carrys out the preset hair Machine parameter region is sent, operating temperature range when in conjunction with the operation of receiver comes the preset receiver parameters region, to avoid this Parameter region is negotiated under certain specific environment to (such as low temperature) when obtaining since external environment variation, such as low temperature become high Temperature, caused by the parameter negotiated at low temperature equipment may be made not work normally under high temperature environment, so as to cause letter The unstable problem in road.Wherein, transmitter, receiver parameters region can respectively include the ginseng of multiple target components for needing to negotiate Number region.For example, what is transmitted on transmission channel between transmitter and receiver is the data of 12Gbps, in 0 DEG C~60 DEG C works Make in temperature range, emulation or test obtain in the insertion loss (IL) of the frequency point of 6GHz being -12dB.In conjunction with the hair of SerDes Send and receive ability, calculate and it is preset obtain transmitter parameter region ranging from C1=[- 7, -3], C3=[- 11, -9] (then should C1, C3 be first object parameter), receiver parameters regional extent be GAIN=[4,26], ADC=[20,44], DFE0=[- 111,50], DFE1=[- 80,40] (then GAIN, ADC, DFE0, the DFE1 are the second target component).Then when transmitter and reception It is corresponding that the targeted parameter value that machine respectively obtains each target component progress parameter negotiation according to respective negotiation algorithm is in this When within the scope of parameter region, negotiate to terminate.For another example if detecting the insertion of the transmission channel between transmitter and receiver It is -25dB that (IL), which is lost, preset can also obtain transmitter parameter region ranging from C1=[- 9, -5], C3=[- 13, -11], connect Receipts machine parameter region ranging from GAIN=[6,28], ADC=[24,50], DFE0=[- 100,60], DFE1=[- 71,43], when Transmitter and receiver carry out the targeted parameter value that parameter negotiation obtains according to respective negotiation algorithm to each target component respectively When within the scope of the corresponding parameter region, negotiate to terminate.To ensure that the parameter energy maximum that the transmission channel is negotiated can Intersymbol interference can be overcome, improve the performance of communication system.

Further, the transmitter 1 is additionally operable to detect the enabled current state of preset negotiation, the current state Including open state or closed state；When detecting that the negotiation is enabled in open state, negotiate according to preset first Algorithm holds consultation to first object parameter, and obtains the first object parameter value obtained after the negotiation；And detecting When stating that negotiation is enabled to be closed, preset parameter setting values corresponding with the first object parameter are obtained, and by institute Parameter setting values are stated as first object parameter value, communication link is established with receiver 2 to be based on the first object parameter value, from And the communication link of the foundation is communicated.

Specifically, the enabled switch of a negotiation parameter can be pre-configured in transmitter, and preset one and first mesh Mark the corresponding parameter setting values of parameter, if send negotiate it is enabled close, directly invoke this and preset join with the first object The corresponding parameter setting values of number using the parameter setting values as the first object parameter value, and skip to receiver parameters negotiation；Such as Fruit send negotiate it is enabled open, then transmitter according to channel IL and/or operating temperature range preset transmitter parameter region into Row parameter negotiation.Similarly, can also be pre-configured with the enabled switch of a negotiation parameter in receiver, and preset one with this The corresponding parameter setting values of two target components, so as to receive negotiate enabled close when, will be corresponding with second target component Parameter setting values as second targeted parameter value, details are not described herein again.

Further alternative, the transmitter 1 is additionally operable to be not at the first object in the first object parameter value When within the scope of the corresponding parameter region of parameter, repeats and described first object parameter is assisted according to default negotiation algorithm Quotient, and the first object parameter value obtained after the negotiation is obtained, and judge the first object parameter value whether in pre- The step within the scope of parameter region corresponding with the first object parameter set, and record the negotiation number of the negotiation；Inspection Whether the negotiation number for surveying record is more than given threshold；It is described to send out alarm if being more than the given threshold.Namely It says, when the parameter negotiation number that transmitter repeats is more than setting value, but parameter is not still in corresponding parameter region range It when interior, then can be alerted, can also be regarded as completing parameter negotiation (such as the ginseng that the last time can be negotiated of this transmitter Numerical value is the first object parameter value that the negotiation terminates) and it is directly entered receiver parameters negotiations process.Further, work as reception When machine parameter negotiation negotiate number be more than setting value, but parameter still not within the scope of corresponding parameter region when, then can carry out Alarm, the alarm processing of the receiver end is similar with transmitter alarm processing, and details are not described herein again.Further, in receiver After the completion of parameter negotiation, if transmitter parameter need to be readjusted, transmitter parameter adjustment is carried out.It does not need such as, then can pass through The first object parameter value and second targeted parameter value are communicated, to improve the negotiation parameter value that parameter negotiation obtains Accuracy, effectively to overcome intersymbol interference.
