Description
[technical field]
The present invention relates to the communications field of software radio, relate in particular to the waveform application based on SCA standard development, is a kind of waveform multichannel treatment system and method based on routing address mapping.
[background technology]
The topmost measurement index of software radio (SDR) is exactly flexibility, and radio waveform does not need to adjust the SDR platform ability of (comprising hardware and the operating environment of waveform application operation) simultaneously by software change.The most widely used SDR software architecture is SCA at present, and SCA has good performance on hardware and software separate design, raising waveform portability.
Waveform application is decomposed into assembly and logical device by SCA.Assembly is software processing module, has input, output and the environmental requirement of clear definition, and is the unit that can dispose.Logical device is abstract to hardware module, can processing information flow.Between assembly and inter-module, assembly and logical device, use CORBA middleware to communicate by letter, for the communication between CORBA and DSP, FPGA, adopt hardware abstraction layer as transducer.SCA provides the deployment based on SCA application and the standard of management is realized to its portability.But all aspects, particularly waveform that the service of SCA to system platform and device A PI interface specification are not enough to cover transplantability are for multichannel adaptability aspect.
SCA2.2.2 standard refers to that conducting communication system realizes one of standard of software radio, and it is as follows that traditional employing SCA2.2.2 standard and hardware abstraction layer are realized the concrete methods of realizing of waveform application:
First, communication waveforms is encapsulated as waveform application software according to SCA2.2.2, is embodied in the territory configuration file of realizing the waveform components of waveform function and describing each inter-module annexation.Comprise following three steps:
The first step: based on the carrier of assembly operating, be GPP assembly (running on PPC), DSP assembly (running on DSP), FPGA assembly (running on FPGA) by component clustering.
Second step: by the help of graphical Integrated Development Environment, complete the UML modeling of assembly, and the transfer of data of the function that need to realize according to waveform to each inter-module and control carries out api interface design and definition, generate waveform IDL interface description document and also compile according to the CORBA middleware of selecting.It should be noted that FPGA and DSP belong to non-CORBA assembly, adopt the method for hardware abstraction layer to realize the transmission of component interface data.
The 3rd step: realize writing of assembly entity and assembly api interface function, compiling link generates practicable code.Write the XML such as component description and assembled territory configuration file, provide the information such as port that assembling logic, deployment relation and each waveform components between waveform components provide/use, and the packing of assembly associated documents is generated to waveform application software kit.
Secondly, it is upper that all waveform application software kits all reside in PPC, while waiting the order that occurs loading certain waveform, then associated component is loaded to assemble according to the description of XML territory configuration file realizes waveform function.
Finally, design user interface adds unloading operation to communication system.
The weak point that this method is adapted to multi-channel system is:
In the time that system has M transceiver channel, which passage waveform is loaded on is determined by XML territory configuration file and its hardware abstraction layer route, and these have designed conventionally in the time of early development, can not change.
For M transceiver channel, method one is to fix certain waveform to load on certain specific passage, only need to compile its XML that loads some passages and corresponding hardware abstraction layer route thereof, do like this integrated communications system and can lack flexibility, once and having passage to damage, this plan runs on the waveform of this passage and cannot normally work.
Method two is corresponding to M transceiver channel, and each waveform is compiled and write respectively, realizes the function that its M transceiver channel all can load.Do like this load document and become large (becoming original M doubly), for the demand of processor resource high (all files are stored on PPC), system cost can uprise.
