摘　　要：建立了一种空时信号传输模型,分析对比了递归最小二乘(RLS)和最小均方误差(LMS)两种算法后,提出了一种基于RLS算法,由智能天线和时域均衡器组成的采用后馈滤波器的空时联合均衡器.仿真结果表明,在多径衰落信道下该方法能有效改善系统抗干扰能力,算法简单且易于实现.A kind of space/time transmission model is set up. After analyzing the recursive least square (RLS) and least mean square (LMS) algorithms, a joint space/time equalizer is presented which is composed of smart antennas and temporal equalizer based on RLS, and adopts rear feedback filter. Simulation results show that the proposed scheme efficiently improves the system anti-interference ability in multi-path fading channel, and gains the practice feasibility and simple algorithm complexity.
