摘要

研究了多线频选信道中多发射/多接收分集技术。为了适应频率选择性衰落中存在的码间干扰，分集技术必须与宽带多载波调制(MCM)相结合。本文介绍了一种用于室内通信的高效空频(SF)编码多音多电平FSK (M3FSK)。仿真结果表明，在高脉冲电力线环境下，SF比单线M3FSK系统的性能提高了5dB。

Multi-emitting/multi-receiving points MMFSK for power-line communications

This paper investigates multiple emitting/multiple receiving points diversity technique for multi-wire transmission over frequency selective multi-wire channels. To be resilient to the inter-symbol interference (ISI) present in the frequency selective fading, diversity technique must be used in conjunction with wide band multi-carrier modulation (MCM). We introduce an efficient Space-frequency (SF) coded Multi-tone M-ary Multi-level FSK (M3FSK) for indoor communications. Simulation results show that there is up to 5dB performance improvement of the SF over single-wire M3FSK systems in highly impulsive power-line environments.
