摘　　要：针对现行TCM编码方法过于复杂、寻码不够灵活的问题,给出了一种新的TCM编码方法。通过分析TCM编码的直观规则,以一位延迟作为输出先画出任一编码器结构,然后转化为多项式表示通过MATLAB函数来验证其网格结构,最后画出状态分析图,写出映射方式。该方法采用一位延迟输出的任意编码器结构,通过网格验证后即可符合TCM编码的直观规则,简化了编码难度,提高了TCM编码的灵活性,并且可以快速写出编码的映射方式,使TCM的编码过程变得更加简捷。A novel TCM coding method is proposed to solve the problem of inflexibility in searching code and high complexity of current TCM coding algorithm. By analysing the TCM coding regulation, this method using one-bit delay as output bit to construct the framework of any coder firstly, transforms it into a polynomial, then tests the network structure via MATLAB function, and plots the picture of state analysis to get mapping mode. This method facilitates the TCM coding and improves the coding flexibility, and the mapping mode of coding can also be obtained quickly, which makes the coding progress more simple and direct.
