Cooperative Space-Time Network Coding for Multi-Sources Distributed Cooperative Network

Article Preview

Abstract:

In this paper, a novel cooperation space-time network coding (CSTNC) scheme based on multi-sources distributed cooperative network is considered. In this scheme, multiple sources transmit signals to relay and destination node. The relay re-encodes the decoded signals through space-time network coding with the aid of multiple antennas. The simulation shows that the BER, capacity and outage probability of the CSTNC becomes better with the increasing of relay antenna number and very close to traditional space-time network coding (TCSTC) scheme. Meanwhile, transmission efficiency analysis demonstrates that CSTNC scheme has higher transmission rate.
