摘　　要：研究相关Nakagami-m衰落信道上采用最大比合并分集接收的M进制相移键控,M进制差分相移键控的平均误符号率性能,采用互补误差函数的方法来计算平均误符号率的上下限。数值计算结果表明该平均误符号率性能上限和下限能够较好地表征相关Nakagami-m衰落信道上M进制相移键控和M进制差分相移键控的平均误符号率性能。Exact closed-form expressions of the average symbol-error rate(SER) for M-ary phase shift-keying(MPSK) and M-ary differential phase-shift-keying(MDPSK) with maximal-ratio combining(MRC) diversity scheme in correlated Nakagamim fading channels have been obtained.The upper and lower bounds of the average SER for MPSK and MDPSK have been investigated.The numerical results show that these bounds on MPSK and MDPSK symbol-error rate can approach their corresponding exact values.

关 键 词：相关衰落信道 误符号率 最大比合并
