摘要 研究相关瑞利衰落信道上MIMO系统中组合发射机选择合并(SC)/接收机最大比合并(MRC)的天线分集系统性能。使用矩生成函数方法,推导相关瑞利衰落信道上采用组合SC/MRC天线分集和相干检测的M进制相移键控(MPSK),M进制正交幅度调制(MQAM),M进制脉冲幅度调制(MPAM)等几种M进制数字调制方式的误符号率精确表达式。数值计算结果阐明相关性和天线阵结构对采用组合SC/MRC天线分集的几种M进制数字调制方式的平均误符号率性能的影响。 A diversity system with combined antenna selection at the transmitter with maximum-ratio combining(MRC)at the receiver for multiple-input-multipleoutput (MIMO)systems in correlated Rayleigh fading channels is investigated in this paper. By using the moment generating function-based analysis approach, closed-form solutions to the average symbol error probability(SEP) of several M- ary modulation schemes(including M-ary phase shift keying(MPSK), M-ary quadra- ture amplitude modulation(MQAM),M-ary pulse amplitude modulation(MPAM)) for MIMO systems with coherent detection are derived. Numerical results illustrate the effect of correlation and antenna configurations on the average SEP of several M-ary digital modulation schemes for MIMO systems.
