摘要

本文对窄带数字调频的跳频扩频系统进行了性能分析，该系统采用限制鉴别器(L/D)检测和检测后的综合滤波。说明了使用编码和子符号分集所提供的性能改进。研究还表明，在部分频带噪声干扰和多径环境下，一个鲁棒性更强、复杂度更低的系统比传统系统性能更好。

Limiter/Discriminator Detection of Narrowband FM in Jamming and Multipath Environments

This paper presents a performance analysis of frequency-hopped (FH) spread spectrum systems for narrowband digital FM with limiter-discriminator (L/D) detection and integrate-and-dump post-detection filtering. The performance improvement provided by using coding and subsymbol diversity is illustrated. It is also demonstrated that a more robust, less complex system can perform better than the conventional system in partial band noise jamming and multipath environments.
