摘　　要：在QPSK调制方式下对瑞利信道的采用Alamouti方法的发端分集和采用MRC方法的收端分集误码性能进行分析比较,并用MATLAB对发端、收端分集技术进行模拟,说明发端分集技术可以取得和收端分集技术相当的性能,并介绍几种简化的发端分集技术。The symbol error of transmitting diversity with Alamouti model is compared to that of receive diversity with MRC under the conditon of QPSK modulation for Rayleigh channel,both two systems are also simulated with MATLAB.Several simplified transmitting diversity technologies are also introduced.
