Turbo乘积码对星间光通信链路的性能改善分析

Performance improvement analysis of TPC coded intersatelliteoptical communication link

通过联合界技术较为详细地给出了Turbo乘积码的最大似然译码限,并比较了在星间光通信链路中Turbo乘积码和Turbo卷积码及传统级联码的纠错性能。研究表明,Turbo乘积码的纠错性能优于传统级联码以及Turbo卷积码。

In this paper, ML decoding bound of TPC assuming transmission over an AWGN channel is given through union bound technique. And the error performance of TPC, PCCC and classical concatenated code in intersatellite optical communication link is compared. Result shows that TPC is better than classical concatenated code and PCCC in error correction in intersatellite optical communication.
