(1) Performance evaluation method of turbo trellis-coded modulation (TGM) is proposed by extending the method for conventional turbo codes and optimum codes have been searched.(2) For random or burst Impulsive noise channel, performance evaluation method of turbo codes and of TCM have been proposed based on a Markov model of the burst impulsive noise and the optimum codes have been searched.(3) For an inter-symbol interference channel, performance evaluation of turbo codes has been proposed and optimum codes have been searched.(4) For a fading channel, performance evaluation of turbo TCM has been proposed for correlated fading based on a Markov model of fading channel.(5) A performance evaluation of a serially concatenated TCM has been proposed.(6) A performance evaluation of product code is examined by using an importance sampling, but the evaluated performance does not coincide simulation results.(7) For turbo TCM, interleaves matched to component codes have been proposed and the usefulness of them has been shown by simulation.

(1)通过对传统Turbo码的性能评估方法进行扩展，提出了Turbo网格编码调制（TGM）的性能评估方法，并对最优编码进行了搜索。(2)针对随机或突发脉冲噪声信道，基于突发脉冲噪声的马尔可夫模型，提出了Turbo码和TCM码的性能评估方法，并搜索了最优编码。(3)针对码间干扰信道，对Turbo码的性能进行了评估，并搜索了最优码。(4)针对衰落信道，基于衰落信道的马尔可夫模型，提出了Turbo TCM在相关衰落信道下的性能评估方法。(5)提出了一种串行级联TCM的性能评价方法。(6)采用重要抽样方法对产品代码进行了性能评估，但评估结果与仿真结果并不吻合。(7)对于Turbo TCM，提出了与分量码匹配的交织器，并通过仿真验证了其有效性。
