认知的协同多输入多输出通信

Cognitive,Cooperative and MIMO Communication for PLC

电力线通信是研究基于现存的有线网络进行低速/高速数据传输的一种通信系统。当前情况下集成系统/智能网通信/数字融合等提供一项新的电力线通信解决方案。由于数据传输在电力网的损耗,需要设计新的方案和技术,因此文中介绍了一种新一代电力线通信系统。同时文中简述了当前PLC技术存在的一些缺点,以及合理利用认知的协同多输入多输出(MIMO,Multiple input and multiple output)通信的潜在益处。

Power line communication is a communication system which is the study of the existing wired network based on low-speed/high-sepeed data transmission. Currently, there is a great interest in providinga anew power line communica tion solution for embedded systems, smart grid communication, and digital inclusion. As the loss of data transmission in the power grids, it need new schemes and techniques. This paper introduced a new generation power line communication systems. It outlined some shortcomings of current PLC technologies and the possible benefits from using concepts of cooper ative, cognitive and multiple input multiple output （MIMO） communications.
