| 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。 |

| Abstract: |
| A novel TCM coding method is proposed to solve th
e problem of inflexibility in searching code and high complexity of current TCM
coding a
lgorithm. By analysing the TCM coding regulation, this method using onebit del
ay
as output bit to construct the framework of any coder firstly,transforms it
into a polynomial, then tests the network structure via MATLAB function, a
nd plots the picture of state analysis to get mapping mode. This method f
acilitates the TCM coding and improves the coding flexibility, and the mapping m
od
e of coding can also be obtained quickly, which makes the coding progress more s
imple
and direct. |
