摘　　要：在跳频技术中,由于边带效应,使接收信号的误码率增高.从理论上分析了跳频系统在最坏干扰下的误码率和最大比值合并问题,讨论利用分集技术,克服跳频系统的边带效应,并给出了仿真结果.The error code rate of receiving symble will increase because of the partial band interference in the frequency- hopped spread spectrum communication system. The worst error probability and the question of maximum rote combination are theoretically analysed, which proves that the partial band interference will improve Rake technology. Finally, the simulating result is given.

关 键 词：跳频技术 误码率 边带效应 分集技术
