无线网络中物理层网络编码策略研究
Study on Physical-layer Network Coding Strategy in Wireless Network
摘要
Abstract
The electromagnetic wave will interfere with each other in the process of transmission in wireless network communications.Physical-layer Network Coding(PNC) reduces the communication interaction between nodes through a proper modulation-and-demodulation technique. PSK is a common physical layer modulation technique, but PSK has phase ambiguity and continuous "0" continuous "1" problem, and cause receive error. A scheme differential phase-shift keying based on PNC-DPSK is proposed, and it is also extended to M-ary differential phase-shift keying. The novel scheme is a solution method to PSK's phase ambiguity and continuous "0" continuous "1" problem, and it also can reduce about 50％ energy consumption in the relay node.关键词
