摘要

本文采用不降低扩频处理增益的多音网格编码调制（MT-TCM）及改进的交织MT-TCM方案来提高跳频/扩频多址系统的性能。对于给定的总跳频带宽、跳速和符号速率

考虑加性白高斯噪声、部分带宽干扰与多用户干扰的综合影响

推导出估计比特错误率的计算公式。给出数值与模拟结果

并与采用卷积编码的跳频/扩频多址系统的性能作了比较。

Abstract

In this paper

the multitone trellis coded modulation（MT-TCM）and the interleaved MT-TCM.which don’t decrease the processing gain of spread spectrum systems

are suggested to improve FH/SSMA system performance.Assuming that the total hopping bandwidth

the hopping rate and symbol rate are all fixed

performance analyses are given when combined effects of additive white Gaussian noise

partialband jamming and multi-user interference are considered.Then

the performance of the proposed system is evaluated numerically by using the derived closed form expressions and compared with that of convolutional coded systems.
