摘要

多天线结合turbo均衡等先进的检测技术是固定无线接入(FWA)系统提供高质量、高数据速率服务的有效手段。本文研究了在频率选择的FWA SUI-3信道上具有两个发射天线和一个或两个接收天线的Alamouti空时分组码(STBC)。本文提出了一种turbo均衡算法,该算法既能利用多径分集,减少码间干扰(ISI)的影响,又能保持原Alamouti检测算法的特征,即通过简单的线性处理实现空间分集。

Turbo Equalization For Space-Time Block Coded FWA Systems
The use of multiple antennas in combination with advanced detection techniques, such as turbo equalization is an effective means for a Fixed Wireless Access (FWA) system to provide high quality and high data rate services. Alamouti's space-time block code (STBC) with two transmit antennas and one or two receive antennas over frquency selective FWA SUI-3 channels is considered in this paper. We propose a turbo equalization algorithm that aims at exploiting the multipath diversity and reducing the effect of intersymbol iterference (ISI), and in the meantime, keeping the desired feature of the original Alamouti detection algorithm, i.e, achieving spatial diversity with simple linear processing.
