摘要
空时编码技术能提高系统吞吐量,改善非对称应用环境中下行链路的传输问题,还可以结合干扰抑制技术,进一步提高系统容量。文章介绍了用于EDGE蜂窝通信系统和宽带无线接入网的空时编码(STC)技术,重点讨论了物理层信道估值、联合均衡与编码以及干扰抑制等信号处理技术。
Space-Time Code (STC) can increase system throughput, and improve downlink transmission under an asymmetric application environment. It can further increase system capacity when combined with interference suppression technique. The paper discusses STC techniques for the EDGE (Enhanced Data Rates for Global Evolution) communication system and broadband wireless access networks, with a focus on such signaling processing techniques as the physical layer channel estimation, combined coding and equalization, and interference suppression.
