摆脱了传统代数译码方法，对分组码进行基于广义阵列码（ＧＡＣ）结构 的网格译码（Ｔｒｅｌｌｉｓ ｄｅｃｏｄｉｎｇ），研究了 Ｒａｙｌｅｉｇｈ衰落信道中分组码与这种软判决最大 似然译码方法相结合的性能。模拟结果显示，分组码采用网格译码，可为移动衰落信 道带来显著的性能改善。
The traditional algebraic decoding method is used to separate the block codes from the trellis decoding based on the generalized array code (GAC) structure. It is studied that the block codes in the Rayleigh fading channel and the soft-decision maximum likelihood decoding method The combination of performance. Simulation results show that the block code using grid decoding, mobile fading channel can bring significant performance improvement.
