中文摘要：

根据空时分组码（STBC）系统的编码特点,提出了一种低复杂度的基于宽线性（WL）处理的Kalman均衡算法。该算法针对STBC系统,利用宽线性处理的思想,采用Kalman均衡算法对接收信号及其复共轭联合进行处理,有效地减轻了由频率选择性衰落信道引起的码间干扰（ISI）。对所提出的均衡算法在不同环境下进行了仿真验证。结果表明,与传统的线性均衡器相比,该算法明显提高了系统的性能,具有实际应用价值。

This paper proposed a low complexity Kalman equalization algorithm based on widely linear（WL） process by utilizing the property of the space time block code（STBC） systems.The proposed equalization algorithm significantly alleviated the effect of inter-symbol interference（ISI） caused by frequency selective fading channel by using WL-Kalman equalizer,which jointly processed the received sequence and its complex conjugate.Gave the simulation results in different scenarios.The resuts show that the proposed WL-Kalman equalization algorithm gets better performance than the conventional linear equalizer.
