摘要
分层空时编码技术是近几年来通信领域新兴的研究方向,它主要用于解决高速无线通信下行传输问题。主要从分层空时编码的技术原理、设计准则及一种典型的译码算法入手,全面地分析了BLAST的特点,并通过仿真对几种典型的译码算法的性能进行了对比。最后对目前的研究动态做了简要的介绍。
The technique of BLAST （Bell Labs Layered Space-Time） has been advancing drastically in recent years. This technique is mainly designed to combat channel fading in downlink transmission. The characteristics of BLAST are analyzed roundly in this paper on its technical theory, design criteria and a typical decoding algorithm; and the performance of several typical decoding algorithms is eompared with the simulation result. Finally the present research tendency is briefly introduced.
