In order to solve the problem of traditional space-time coding cooperation scheme with higher power consumption and lower data transmission efficiency, this paper proposes a novel Cooperation Space-time Network Coding(CSTNC)scheme in cooperation networks with multiple sources and single relay. The CSTNC scheme takes advantage of multiple antennas to obtain receiving diversity, and designs space-time network coding at relay node. Then the relay transmits signals to destination node depending on the encoding ...
1引言(Traditional Routing,TR)方案,中继仅用于转发信号,分布式协作通信模型[1]常与空时分组码相结合构且在每个时隙转发单个信号。此外,传统协作空时编码成,进一步提高了系统性能和分集增益,分布式协作系(Traditional Cooperation Space Time Coding,TCSTC)统每次传输时不再?
