摘要
基于准正交空时分组码的时域均衡技术提出一种新的块预编码方法。该方法将平坦衰落信道符号编码扩展到时域上数据块编码,构造了一种嵌入式准正交结构,从而简化了接收端信号处理,降低了复杂度。同时,对准正交空时分组码部分解耦和全解耦两种方式进行了比较,蒙特卡罗仿真结果证明了该方法的优势。
The proposed schemes presents a new block precoding method based on time domain equalization for QO-STBC and extends the original symbol-level scheme developed for fiat-fading channels to a block-level implementation in the time domain. Receiver structures exploite the embedded quasi-orthogonal structure to design low-complexity receivers.This paper also eompares partial decoupling with full deeoupling.Monte Carlo simulation results confirm the superiority of proposed scheme.
