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.

拟议的研究计划旨在提高格子编码调制的性能。 Trellis编码调制（TCM）改善了数字传输的噪声性能，而无需增加所需的带宽或降低有效数据速率。性能提高以特定的数据速率降低了传输的功率要求。 %%％主要目标是研究分析评估TCM代码距离的方法。在开发一种评估TCM代码距离的简单，有效的方法时，将促进代码的比较。此外，希望分析评估方法将导致一种代码设计方法，从而提高TCM代码性能。评估技术将通过计算机模拟确认。
