快跳扩频通信系统中一种抗部分带宽干扰的方案

A Scheme for FFH/SS Communication Systems Efficiently Rejecting the Partial Band Jamming

本文提出一种用于快跳扩频系统以抵抗部分带宽干扰的分集分组加权合并技术,推导出采用该方案的 BFSK 调制快跳系统的比特错误率公式,文章最后分析新方案抗任意部分带宽干扰的能力,分析结果表明:分组加权合并方案能显著提高系统抗部分带宽干扰的性能。

This paper presents a diversity combining technique which is called as Diversity Packetz- ing-Weighting Combining(DPWC),as can be used for rejecting partial band interference in fast frequency hopping system.A Bit-Error-Rate(BER)formula is derived for the FFH/SS system using Binary Frequency Shift Keying(BFSK)modulation.And the capability of the new scheme to reject any Partial Band Jamming(PBJ)is analysed.It is shown from the ana- lytical results that the proposed combining scheme can improve the performance of the sys- tems to reject PBJ notably.
