为解决采用最小均方误差(MMSE)信道预测的发射天线选择(TASP)/接收天线最大比合并(MRC)的无线通信系统设计问题,利用抛物柱面函数以及高斯Q函数的近似表达式和矩生成函数(MGF)法,分别推导了瑞利块衰落信道上采用 TASP/MRC 天线分集的相干检测 M 进制正交和双正交信号的平均误符号率(ASER)精确表达式以及正交信号ASER的近似表达式。数值计算和仿真结果验证了采用TASP/MRC和相干检测的正交/双正交ASER精确表达式的正确性以及正交信号ASER近似表达式的准确性。上述M进制正交/双正交信号ASER精确或近似表达式,可用于设计采用相干检测M进制正交和双正交信号的TASP/MRC天线分集系统,并能够快速地确定收发天线数和信道预测器级数等参数,避免耗时的计算机仿真。
In order to solve the design problem of predictive transmit antenna selection (TASP) / receive antenna maximum ratio combining (MRC) wireless communication system with the minimum mean square error (MMSE) channel prediction
exact and approximate closed-forms for the average symbol error rate (ASER) of M-ary ortho-gonal and biorthogonal signals with coherent detection and TASP/MRC over Rayleigh block fading channel were de-rived by using parabolic cylinder function
the approximate expression of Gaussian Q-function and moment generat-ing function (MGF) based analysis approach respectively.Numerical and simulation results show that the theoretical analysis of the ASERs of orthogonal and biorthogonal signals is exact and the approximate closed-form for the ASER of orthogonal signals is accurate.The above exact or/and approximate closed-forms of ASER of orthogonal and biortho-gonal signals with coherent detection and TASP/MRC can be used to determine the number of antennas of transmitter and receiver and the parameters of predictor quickly
instead of the time-consuming and inefficient computer simulation.
