编码的非相干混合DS—SFH MFSK调制扩频rn通信系统在部分带宽多频干扰时的性能分析

摘要

The performance of MFSK modulation noncoherent hybrid DS-SFH spread spectrum communication systems with partial band multitone jamming is analyzed.On this basis the performance of MFSK modulation noncoherent hybrid DS-SFH spread spectrum communication systems that employ forward-error-control coding is analyzed and compared, the coding schemes analyzed include: Reed-Solomon codes (error-only decoding) and dual-k convolution codes. At the same time, the effects of partial band noise interference and forward-error-control coding on the hybrid spread spectrum system performance are discussed and analyzed.%本文针对部分带宽多频干扰（partial band multitone jamming）信道环境下，MFSK调制非相干混合DS－SFH扩频通信系统性能研究的基础上，对使用RS（V，K）码和双k卷积码等几种不同前向纠错信道编码的MFSK调制非相干混合DS－SFH扩频通信系统性能进行了分析、计算和比较。同时分析和讨论了部分带宽噪声干扰、前向纠错编码等对系统性能的影响，得到一些重要结果。
