Description: 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)／4t-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。-Research related to Rayleigh fading MIMO channel transmitter system to choose the combined portfolio (SC)/4t-collection machine maximal-ratio combining (MRC) diversity antenna system performance. The use of moment generating function method, Rayleigh fading channel is derived using the relevant combination of SC/MRC antenna diversity and coherent detection of M-ary phase shift keying (MPSK), M M-ary quadrature amplitude modulation (MQAM), M-band pulse amplitude modulation (MPAM), such as several M-band digital modulation modes of expression of symbol error rate of accuracy. The numerical results clarify the relevance and structure of antenna arrays using combinations of SC/MRC antenna diversity of several M-band digital modulation of the average symbol error rate performance.
