物理层网络编码系统中ARQ的设计
ARQ design for physical-layer network coding system
摘要
Abstract
In the physical-layer network coding system,TO-ARQ (Terminal-only ARQ) is a common approach to provide error control at the link-layer.For TO-ARQ system has the problems of slow data transmission rate and large delay,this paper proposes a TR-ARQ(Terminal-relay ARQ)scheme based on TO-ARQ.In this scheme,if the network coded packet in error at relay,the relay will feed back messages to inform the two terminals to retransmit the corresponding data packets,thereby reduce the feedback delay of data transmission.The experimental results show that,compared with TO-ARQ,the TR-ARQ scheme improves the system delay and data transmission rate significantly.关键词
