摘要 为了降低接收端译码器的译码复杂度,提出了一种能降低译码复杂度的STC算法。对码字矩阵进行设计,利用最大似然译码算法分析接收信噪比特性。通过MATLAB仿真所得结果表明,文中提出的算法与Viterbi译码算法引比,虽具有相当的译码性能,但译码复杂度大大降低。 In order to reduce the decoder complexity,a kind of algorithm of STC that can reduce the decoding complexity is put forward.By designing the matrix of code words,the ML decoding algorithm is used to analysis signal-to-noise characteristic.The results of the MATLAB simulation shows that the algorithm proposed has a comparable decode performance with Viterbi decoding algorithm,but has a much lower decoding complexity.
