低压电力线通信研究进展综述

The Research Progress of Low Voltage Power Line Communication

电力线通信(PLC)是以现有配电网为媒介的一种通信方式,具有组网迅速、经济方便、不需重新布线等优点,是有效解决用户终端接入宽带网络的"最后一公里"问题的最具有优势的方案之一。现在对PLC的研究已经从单入单出(single-input-single-output,SISO)系统向多入多出(multiple-input-multiple-output,MIMO)系统发展。MIMO-PLC系统具有速度更快、信道容量更大等优点。从SISO-PLC和MIMO-PLC研究所涉及的信道模型、噪声建模、标准、电磁兼容以及硬件仿真平台等方面进行了综述介绍。

Power line communication（PLC） is a kind of communication mode using the existing distribution network,which is convenient and economical for networking,without rewiring.Power line communication is thus one of the most advantageous solutions which could solve the ＂last kilometer＂problem of the access of user terminal in broadband network.The research on PLC is evolving from single-input-single-output（SISO） system to multipleinput-multiple-output（MIMO） system,with the advantages of faster speed and larger capacity.The typical channel models,noise models,standards,electromagnetic compatibility and hardware simulation platform related to SISOPLC and MIMO-PLC research are introduced.
