拟议的研究计划，以提高性能的 网格编码调制网格编码调制（TCM）提高了 数字传输的噪声性能不增加 所需的带宽或降低有效数据速率。的 性能的提高降低了 以特定的数据速率传输。 %%% 主要目标是研究分析方法， 对TCM编码的距离进行评价。在开发一个简单的， TCM编码距离有效评估方法， 代码将被简化。此外，希望 分析评估方法将导致代码设计方法 这提高了TCM码的性能。评价技术将 通过计算机模拟来证实。

The proposed research plans to improve the performance of trellis coded modulation. Trellis coded modulation (TCM) improves the noise performance of digital transmission without increasing the required bandwidth or reducing the effective data rate. The performance improvement reduces the power requirements for transmission at a specific data rate. %%% The primary goal is to investigate methods of analytically evaluate the distance of TCM codes. In developing a simple, effective method to evaluate TCM codes distances, comparison of codes will be facilitated. In addition, it is hoped that the analytical evaluation method will lead to a code design method which increases TCM code performance. The evaluation technique will be confirmed by computer simulations.
