摘　　要：设计了频率选择信道基于RLS算法的自适应判决反馈均衡MIMO-DFE空时接收机,由于这种接收机不需要信道识别,从而降低了接收机的复杂度。通过蒙特卡罗仿真评估了接收机在频率选择信道下的误符号率性能。仿真结果表明,在不加信道编码的情况下,该接收机在信噪比为 14dB时误符号率达到 10-3以下。An adaptive Multi Input Multi Output(MIMO) decision feedback equalization(DFE) space-time receiver based on RLS algorithm is introduced. No channel identification is required for the proposed adaptive receiver so that the computation complexity is reduced. The performance of the symbol error rate in frequency selective channels is investigated by Monte Carlo simulation. The results show that the required Signal-to-Noise Ratio(SNR) to ensure the symbol error rate below 10^(-3) is approximately 14dB without channel coding.
