摘要/Abstract

摘要：

提出了将 Cayley差分酉空时码应用于多输入多输出电力线通信系统的方案。发射端，首先将待编码的所有子流映射为斜Hermit矩阵，然后将复斜Hermit矩阵张成的线性空间映射为高度非线性Stiefel流形表征的各向同性的酉矩阵星座，并借此以差分模式通过一个分块衰落的多输入多输出电力线信道传输信号；接收端，基于表征数据流的Cauchy随机变量的无约束解，诱导出发送信号的近似线性最大似然估计。仿真结果表明，在高信噪比的条件下，本文提出的方案可实现高速率电力线数据通信。

Abstract:

The application of Cayley differential unitary space-time code in MIMO power line communication system was studied.The linear space of complex skew-Hermitian matrices was mapped to isotropic unitary matrix constellations represented by highly non-linear Stiefel manifolds,by which signals were transmitted through a block fading multiple input multiple output power line channel with in a differential mode.Finally,based on the unconstrained solution of the Cauchy random by which data streams were represented,the approximate linear maximum likelihood estimation of the transmitted signal was induced.Simulation results show that although the performance of the proposed scheme is slightly lower than that of the system based on orthogonal differential space-time code in terms of bit error rate and diversity gain,it can ensure high-speed and reliable communication at higher signal-to-noise ratios,and is suitable for multi-input multi-output power line communication systems requiring high-speed data transmission.

Key words: multiple input multiple output power line communication, differential space-time code, unitary constellation, Cayley transform
