EDGE＋系统中MMSE—PIC接收机性能分析

摘要

MMSE-PIC receiver is proposed for EDGE+ wireless communication system. The detailed implementation is introduced and compared with the classical RSSE receiver. Based on simulation, the performance of two receivers is compared under different channel fading. Simulation results show that: in AWGN channel, MMSE-PIC gets 1.2dB gain and 0.6dB in TU50 channel.%针对EDGE＋系统中的高阶调制，提出了基于最小均衡误差的并行干扰抵消（MMSE—PIc）算法及其实现方案，对比了经典的RsSE算法接收机与MMSE—PIC算法接收机的处理流程；通过数值仿真详细分析两种接收机在不同信道配置下的链路性能。仿真结果表明：在高斯信道下，相比于RSSE接收机，MMsE—PIc约有1．2dB增益；在TU50信道环境下。约为0．6dB增益。
