Correcting Code Design And Implementation Of Software Radio

Software Radio is a new kind of system,which put forward recently to implement wireless communication. Its central idea is to put ADC and DAC closely to the'antenna,and use software to define all kinds of functions as more as possible. Therefore,Software Radio has greatly mobility and opening. Being of these characterics,it has become one of the focuses of communication research at present.In this paper,error-correcting codes of Software Radio is discussed. The scheme of implementation of error correcting codes is proposed for the VHF/UHF Software Radio Transceiver,which consists of BCH encoder,TCM encoder,interleaver in the transmitter and their counterparts in the receiver:BCH decoder,Viterbi decoder and deinterleaver.First,the history of Software Radio and the overall scheme of VHF/UHF Software Radio Transceiver will be introduced in this paper,then all function modules and their implementation of error correcting codes will be described one by one according to chapters,and finally the design and implementation of this part will be summarized.
