| Abstract: | Physical layer network coding is a promising technique to improve spectral efficiency and network capacity of cooperative relay system, and high order digital modulation techniques are also the effective methods to improve the transmission rate for communication system. This paper analyzes and evaluates bit error rate and throughput in a joint cooperative network coding with modulation system, and a power allocation scheme is also presented. The computer simulation shows that by the deployment of higher-order modulation cooperative network coding system can improve system throughput and also achieve the low frame error rate requirement. |
