摘要

目前，人们正在研究多输入多输出(MIMO)概念的使用，以提高电力线通信(PLC)系统的性能，但很少有人关注如何将其应用于改进基于单载波(SC)调制的窄带技术。设计了一种用于窄带PLC的多输入单输出(MISO)-SC系统，并考虑了反馈信道信息在MISO-SC系统中的适用性。在室外PLC信道和由背景和脉冲分量组成的加性噪声条件下的仿真结果表明，具有部分反馈信道信息的MISO-SC系统的性能优于无反馈的MISO-SC系统和有反馈信道和无反馈信道的SISO-SC系统。

MISO single-carrier system with feedback channel information for narrowband PLC applications

Nowadays, the use of multiple-input multiple-output (MIMO) concepts is being investigated to improve performance of power line communication (PLC) systems, however few attentions have being put on how it can be applied to improve narrow-band technologies based upon single-carrier (SC) modulation. In this paper, a multiple-input single-output (MISO)-SC system for narrowband PLC is devised and the applicability of feedback channel information into the MISO-SC system is considered. Simulation results with outdoor PLC channels and additive noise composed of background and impulsive components indicate that the MISO-SC system with partial feedback channel information can surpass the performances of MISO-SC without feedback and SISO-SC system with and without feedback channel.
