摘要
通过对DS-FH系统DPSK、MFSK两种调制方式下的DS/FH系统模型分析,研究在部分频带噪声干扰下,DS/FH系统性能的影响。结果表明,在发射功率、解调方式等参数相同时,其平均误码率(或相同允许的用户数)优于FH系统。由于DS/FH系统比DS系统能更有效的使用交织技术、且比FH通信系统有更强的多址能力,使其系统性能更加优越,因而获得广泛应用。
In this paper,DPSK and MFSK modulation model of DS-FH system are analyzed, the performance of DS-FH system in partial band noise interference is discussed. It showed that the application of DS-FH system is extensive with the more effective interleaving technology using and stronger multiv address ability,while the sameness of the emission power,demodulation method,and so on.
