Abstract


With the steady growth of new wireless services and standards, single purposedevices with dedicated hardware resources can not meet the needs of users.Software-defined radio has been more flexibility and openness to people of all ages. Atthe same time, with the development of wireless communication technology, the reliabletransmission of information requirements continues to increase, error control coding isone of the important means, it is necessary to study the typical error control coding insoftware radio.In order to meet the flexibility of the channel coding rate and pattern choices,providing commonly used channel coding and decoding, so that users do not need toworry about its internal structure, this is very convenient for them,we need to designsome of the typical channel error correcting code waveform componets to verify itsfeasibility.First, against typical convolutional code, BCH code and RS code encoding anddecoding structure, without changing the complexity of the algorithm, we can provide avariety of code options, including:(2,1,3), and (2,1,7), truncated convolutional codes;(2,1,9),(3,1,9), tail convolutional codes;(7,4),(15,5), and (15,7) BCH code;and (31,15),(255,239),(255,223) and (204,188) RS code;Second, we use the m language in Matlab and Simulink link simulation to verify thecorrectness and feasibility of the above code encoding and decoding structure;Again, based on the idea of modular, defining a software interface for the typicalerror-correcting code in VS2005environment, giving a specific meaning of theparameter list in the function prototype and encoding flow chart, and developing thespecific software code;Finally, joint Matlab and VS2005, test on the functionality and performance for thedeveloped modular function, the difference between test results and Simulink error ratesimulation curve is not more than0.5dB.In this paper I designed and developed typical channel error-correcting codeswaveform components of software radio, the waveform of a typical channel errorcorrecting code becomes a separate module, and completes the development of channelcoding software, through testing, it’s difference with Simulink simulation error ratecurve is not more than0.5dB. In the software implementation of the viterbi decoding,decoding efficiency is improved by100times through the combination of algorithm andsoftware; providing the necessary parameter settings only, it can meet the requirementsof the majority cases,it also provide a reference value for the independent ideology ofsoftware radio module.
