| 摘 要： | 推导了部分频带干扰最佳干扰系数表达式并进行了仿真验证,描述了多进制频移键控/快跳频(MFSK/FFH)系统、衰落信道和分集合并算法模型,在最坏部分频带干扰和衰落信道下,仿真对比了MFSK/FFH系统采用线性分集合并、限幅线性分集合并、自归一分集合并、排序统计自归一分集合并、乘积分集合并5种分集合并算法时的误码率性能,结果表明:在最坏部分频带干扰和衰落信道下,线性合并性能较差,其他4种算法性能较为相似,Rayleigh衰落信道中排序统计自归一分集合并和乘积分集合并算法性能最优。

| Abstract: | The jamming coefficient expression for the worst case partial band jamming(WCPBJ) on the AWGN channel is derived here and then the models of multi-frequency shift keying/fast frequency hopping(MFSK/FFH) system,fading channels and diversity combining schemes are analyzed.BER performances of MFSK/FFH system for different diversity combining schemes are simulated and discussed,such as linear combining(LC),clipped linear combining(CLC),normalized envelop detection(NED) and order statistics(OSNED) and product co... |
