信道预测和联合收发分集的RQAM误符号率性能分析
Symbol Error Rate Performance Analysis of RQAM with Channel Prediction and Joint Transceiver Diversity
摘要
Abstract
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) Wiener channel prediction,the exact and approximate expressions for the Average Symbol Error Rate (ASER) of the Rectangular Quadrature Amplitude Modulation (RQAM) and Differentially Encoded Quadri-Phase Shift Keying (DE-QPSK) are derived by using moment generating function method and approximate expression of Gaussian Q-function,respectively over time-selective Rayleigh block fading channel.The numerical and simulation results verify that the exact and the approximate ASER analysis of RQAM and DE-QPSK is correct and accurate.The obtained exact and approximate expressions for the ASER of RQAM and DE-QPSK modulation can be used to evaluate the impact of transceiver antenna number,channel predictor parameters and various channel parameters on the ASER performance.关键词
