It will be understood that when an element is referred to as being "connected" or "coupled" to another element, it can be directly connected or coupled to the other element or intervening elements may also be present. Further, "connected" or "coupled" as used herein may include wirelessly connected or wirelessly coupled. As used herein, the term "and/or" includes all or any element and all combinations of one or more of the associated listed items.
The terms referred to in this application will first be introduced and explained:
MIMO technology is intended to improve the capacity and spectrum utilization of a communication system by a multiple without increasing the bandwidth. It can be defined that there are many independent channels between the sending end and the receiving end, that is, there is sufficient space between the antenna units, so that the correlation of signals between antennas is eliminated, the link performance of signals is improved, and the data throughput is increased.
The inventors of the present application have conducted research to find that the antenna group 1 of the communication terminal using the MIMO technology has a plurality of independent antennas. Taking 4-antenna MIMO as an example, 4-antenna MIMO means that there are 4 antennas in the communication terminal to connect 4 channels with corresponding signals. Because the communication terminals have hardware difference in production, the transceiving parameters of each channel have deviation inevitably, and in order to ensure that the delivery performance of each channel of the communication terminals is consistent, the compensation is required through calibration.
Currently, due to space and cost considerations, it is difficult to implement detection for each channel because the number of detection interfaces available for calibration measurement is less than the number of channels, and therefore the following two schemes are mainly adopted in the existing MIMO calibration:
the existing scheme I is as follows: only the channel corresponding to one or more antennas of the communication terminal is calibrated, and the obtained calibration data is multiplexed to the channels corresponding to other diversity antennas. That is, only the deviations of the channels corresponding to the antennas RX0 and RX1 are detected and calibrated, and the obtained calibration data of the channels corresponding to the antennas RX0 and RX1 are respectively multiplexed on the channels corresponding to the antennas RX2 and RX3, that is, the channels corresponding to the antennas RX2 and RX3 are not detected, but only the data is multiplexed to realize calibration.
The existing scheme is as follows: and detecting channels corresponding to the antennas RX2 and RX3 of a plurality of standard prototypes, and multiplexing the obtained calibration data as standard data on other communication terminal products by taking the weighted average of the obtained calibration data. At this time, only the standard prototype is configured with the detection interface corresponding to the number of channels, namely, only two test sockets for detecting the channels corresponding to the antenna RX0 and the antenna RX1 are arranged on the communication terminal product.
Therefore, the existing MIMO calibration scheme mainly adopts a multiplexing calibration mode, that is, the calibration data of one or more channels in the detected communication terminal is multiplexed into other channels of the detected communication terminal, or the calibration data of a standard prototype is multiplexed into corresponding channels of the detected communication terminal. Obviously, the multiplexing result cannot perfectly adapt to the personalized deviation compensation of all channels, and the delivery performance of the communication terminal is limited.
The present application provides a communication module, a signal calibration system and a method thereof, which are intended to solve the above technical problems in the prior art.
The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments.
An embodiment of the present application provides a communication assembly, a schematic structural diagram of which is shown in fig. 1, including: the antenna group 1, the line selector 3 and the signal processor 2; the line selector 3 is in communication connection with the antenna group 1 and the signal processor 2;
in a working state, a plurality of antennas in the antenna group 1 are in one-to-one corresponding signal communication with a plurality of channels of the signal processor 2 through the line selector 3;
in a signal calibration state, the line selector 3 is in signal communication with one antenna in the antenna group 1 and each channel of the signal processor 2 one by one, and is used for being matched with the detector 4 to be in communication connection with one antenna in the antenna group 1 so as to realize signal measurement of each channel of the signal processor 2;
the signal processor 2 has a first interface 21, and the first interface 21 is used for being in communication connection with the upper computer 5, so as to realize signal calibration of a corresponding channel of the signal processor 2 according to the signal value measured by the detector 4.
In this embodiment, the line selector 3 is a communication bridge between the antenna group 1 and the signal processor 2, and the line selector 3 may implement one-to-one signal communication between a plurality of antennas in the antenna group 1 and a plurality of channels of the signal processor 2, or implement one-by-one signal communication between a certain antenna in the antenna group 1 and a plurality of channels of the signal processor 2.
When the line selector 3 is in a state of communicating the signals of the antennas in the antenna group 1 with the channels of the signal processor 2 in a one-to-one correspondence manner, the line selector, the antenna group 1 and the signal processor 2 can form a multi-channel antenna system in the MIMO technology, so that the signal receiving sensitivity and the information throughput rate of the communication component in the working state are improved.
When the line selector 3 is in a state of communicating one antenna in the antenna group 1 with a plurality of channels of the signal processor 2 one by one, it can cooperate with the detector 4 to realize the detection of all channels in the signal processor 2. In the detection process, the detector 4 only needs to be in communication connection with one antenna in the antenna group 1, all channels in the signal processor 2 can be detected, the communication assembly only needs to leave one detection interface to realize detection, the detector 4 also only needs to be configured with one detection line 41 to complete detection, the detection hardware and the structure of the detected hardware can be simplified, and the construction difficulty of a factory calibration station can be reduced. Moreover, deviation compensation can be favorably carried out on the calibration equipment such as the upper computer 5 and the like according to the personalized hardware difference of each channel in the signal processor 2, and the delivery performance of the communication terminal can be greatly improved.
For a 4-antenna MIMO communication module, the line selector 3 may alternatively employ a 4P4T (4-pole 4-throw) type selector.
The inventors of the present application consider that, in the signal calibration state, the line selector 3 needs to signal-communicate one antenna of the antenna group 1 and each channel of the signal processor 2 one by one. To this end, the present application provides one possible implementation for the line selector 3 as follows:
as shown in fig. 1, the line selector 3 of the embodiment of the present application includes: a plurality of first signal terminals 31, a plurality of second signal terminals 32, and a plurality of line selection members (not labeled).
The first signal terminals 31 are in one-to-one correspondence communication connection with the antennas in the antenna group 1.
The second signal terminals 32 are in one-to-one correspondence communication connection with the channels of the signal processor 2.
One end of each line selection member is connected to one of the first signal terminals 31 in communication, and the other end of the line selection member is connected to each of the second signal terminals 32 in communication one by one in an on-off manner.
In the present embodiment, the first signal terminals 31 of the line selector 3 are located on the antenna side of the line selector 3, and are used for one-to-one communication connection with the antennas of the antenna group 1. The second signal terminals 32 of the line selector 3 are located on the signal processor 2 side of the line selector 3, and are used for one-to-one communication connection with the channels of the signal processor 2.
Each line selection element of the line selector 3 is in fixed communication connection with one first signal terminal 31 on the antenna side, and each line selection element is in communication connection with each second signal terminal 32 on the signal processor 2 side in an on-off manner, so that any one antenna in the antenna group 1 can be connected with each channel of the signal processor 2. The switching between the working state and the signal calibration state of the communication assembly can be realized by controlling each line selection piece. Specifically, the signal processor 2 side of the line selection parts is controlled to be in one-to-one corresponding signal connection with the second signal terminals 32, so that the communication assembly can be switched to a working state; the signal processor 2 side of one line selection element is controlled to be in signal connection with each second signal terminal 32 one by one, so that the communication assembly can be switched to a signal calibration state.
Based on the same considerations as above, the present application provides another possible implementation for the line selector 3 as follows:
as shown in fig. 1, the line selector 3 of the embodiment of the present application includes: a plurality of first signal terminals 31, a plurality of second signal terminals 32, and a plurality of line selection members (not labeled).
The first signal terminals 31 are in one-to-one correspondence communication connection with the antennas in the antenna group 1.
The second signal terminals 32 are in one-to-one correspondence communication connection with the channels of the signal processor 2.
One end of each line selection member is connected with each first signal terminal 31 in a communication mode in an on-off mode, and the other end of each line selection member is connected with one second signal terminal 32 in a communication mode.
The present embodiment is different from the previous embodiment in that each line selection element of the line selector 3 is connected in a communication manner in an on-off manner to one first signal terminal 31 on the antenna side, each line selection element is connected in a fixed communication manner to each second signal terminal 32 on the signal processor 2 side, and any one antenna in the antenna group 1 can be connected to each channel of the signal processor 2. The switching between the working state and the signal calibration state of the communication assembly can be realized by controlling each line selection piece. Specifically, the signal processor 2 side of the line selection parts is controlled to be in one-to-one corresponding signal connection with the first signal terminals 31, so that the communication assembly can be switched to a working state; the signal processor 2 side of one circuit selection element is controlled to be in signal connection with each first signal terminal 31 one by one, so that the communication assembly can be switched to a signal calibration state.
The inventors of the present application consider that a specified change in the signal-on state of the line selector 3 requires control and driving. To this end, the present application provides one possible implementation for the line selector 3 as follows:
as shown in fig. 1, the line selector 3 according to the embodiment of the present application further includes: a drive mechanism (not depicted), a power source 34 and a second interface 33.
The drive mechanism is in driving connection with the line selector for driving the line selector in signal communication with the assigned first signal terminal 31 and second signal terminal 32 to implement the line selector 3.
The power source 34 is electrically connected to the drive mechanism.
One end of the second interface 33 is in communication connection with the driving mechanism, and the other end of the second interface 33 is used for being in communication connection with the upper computer 5 or the control device.
In this embodiment, the driving mechanism is used for driving the line selection component to communicate with the designated first signal terminal 31 and the designated second signal terminal 32, so as to help the communication component switch between the working state and the signal calibration state, and help one antenna to communicate with the plurality of channels of the signal processor 2 one by one in the signal calibration state of the communication component.
The driving instruction of the driving mechanism may be sent by the upper computer 5 or other control devices, and specifically, the upper computer 5 sends the driving instruction signal to the line selector 3 through the second interface 33 of the line selector 3.
The power supply 34 is used to provide the required power to the drive mechanism. Alternatively, the power supply 34 may be integrated independently of the line selector 3, or may share the power supply with other electrical components of the communication terminal provided below.
Based on the same inventive concept, the embodiment of the present application provides a communication terminal, including: a communication assembly as in any one of the embodiments above.
In this embodiment, since the communication terminal employs any one of the communication components in the above embodiments, the communication terminal has the corresponding technical principles and advantages of the above embodiments, and details are not described herein.
Based on the same inventive concept, the embodiment of the present application provides a signal calibration system, as shown in fig. 2, including any one of the communication components provided in the above embodiments, or based on the communication terminal provided in the above embodiments, further including a detector 4 and an upper computer 5.
The detector 4 is connected with one antenna of the antenna group 1 in the communication assembly in a communication way.
The upper computer 5 is in communication connection with a second interface 33 of the line selector 3 in the communication assembly.
The detector 4 is in communication connection with the upper computer 5.
In this embodiment, the upper computer 5 can control the line selector 3 to switch the communication module between the working state and the signal calibration state, and to enable one antenna to be in signal communication with a plurality of channels of the signal processor 2 one by one in the signal calibration state of the communication module, so that the detector 4 can detect each channel of the signal processor 2 from one antenna of the antenna group 1. The upper computer 5 can calibrate the signal of the corresponding channel of the signal processor 2 according to the signal value of each channel.
Therefore, the communication assembly can realize detection only by reserving one detection interface, and the detector can finish detection only by configuring one detection line, so that the detection hardware and the structure of the detected hardware can be simplified. Deviation compensation is carried out according to personalized hardware difference of each channel in the signal processor, and delivery performance of the communication terminal can be greatly improved.

In the whole detection process, only the detector 4 is in communication connection with one antenna in the antenna group 1, so that the detection operation can be simplified. And because the signal value of each channel in the signal processor 2 can be measured (namely the deviation of each channel can be obtained), the upper computer 5 can compensate the deviation according to the personalized hardware difference of each channel in the signal processor 2, and the delivery performance of the communication terminal can be greatly improved.
