2 . aiming at the convolutional code with long encoding restriction we adopt the fano sequential decoding algorithm to implement the decoder 2 、針對編碼約束度比較大的卷積碼,采用fano序列譯碼算法來實現譯碼。
However , the sequential decoding algorithm is not fully developed because of its complication and limited range of application , which lead to relatively few materials particularly in board 而卷積碼的序列譯碼方法因為其硬件復雜度高和應用范圍小,并不十分流行,相關的參考文獻也很少,尤其在國內,相關的研究非常少。
The iess 309 standard indicates two decoding methods , we focus on the systemic convolutional code with long encoding restriction which is 36 bit and adopt the fano sequential decoding algorithm to implement the decoder 在協議中規定了兩種譯碼的方式,我們主要是針對編碼約束度為36的系統卷積碼,采用fano序列譯碼算法來實現其譯碼,并進行了仿真。
In order to implement the iess 309 standard and sequential decoding for the convolutional codes in satellite digital receiver , we have made a deep research in sequential decoding algorithm and solved some problems on implementing the sequential decoder for convolutional codes 為了實現iess309協議標準,在衛星數字接收機中實現卷積碼的序列譯碼,我們深入的研究了序列譯碼算法,解決了序列譯碼器實現的過程中存在的一些問題。
