Performance Analysis of Cooperative ARQ with Code Combination over AF Relay
Fan Xue-lin · Communications technology · 2013
In Cooperative Communication,through combining the multiple adjacent nodes in an area to form a virtual MIMO array,the traditional MIMO transmission results could be achieved.If the multiple signals are combined at the receiving end,the system capacity could be further increased and the transmission reliability(lower error rate) be effectively improved.This paper focuses on the performance of cooperative automatic repeat request(CARQ) in adoption of coherent equal gain code combination at the destination over multi-relay conditions.The analysis indicates that the use of code combination at destination could effectively improve the frame-error-probability(FER),and with the increase of relay number,the FER is reduced.
