  1. We put the emphases on the soft output viterbi algorithm ( sova ), which is one of turbo code ’ s decoding algorithms, and presents the derivation and computation step of the sova decoding algorithm. after presenting sova and map decoding algorithms and analyzing four kinds of decoding algorithms, the paper makes a comparison among the different decoding algorithms by emulation analysis, and analyzes the time complexity of various algorithms, and then contrasts them. in the last part of this paper, according to the criterion recommended by the consultative committee for space data systems ( ccsds ), including code rate,

    根據空間數據系統顧問委員會( ccsds )為turbo碼應用於深空通信系統推薦的標準,包括碼率、碼塊大小、分量碼類型、約束長度、碼生成多項式,以及交織器的選擇等參數的建議以及sova譯碼演算法的理論基礎,設計了sova演算法的實現結構,通過模擬驗證了本文所採用的turbo碼的性能,從而證明turbo碼確實是一種很好的通道糾錯編碼方式,它適用於要求功耗低或信噪比低的深空通信系統中。
