Outage Probability Analysis of Multi-relay Cooperative Communication System
Hou Sheng Jia · Communications technology · 2012
Cooperative diversity could promote data transmission rate and improve the stability of data transmission.Cooperative communication takes a mobile platform with an antenna,which shares other mobile users' antenna in a multi-user environment,thus to produce multiple virtual antennas obtain corresponding diversity gain and improve the performance of mobile communication system.The study indicates that in umulti-relay cooperative communication,asymmetric channel,with relay transmission in amplify-and-forward(AF) mode,exhibits fairly low link outage probability under repetition-based relay and opportunistic relay,thus resulting in remarkable improvement of the system performance.
