Abstract：In order to improve the system performance and reduce the algorithm complexity future, a new better approximate analysis method named equivalent chi-square distribution method is proposed in cooperative communication systems. More accurate theoretical expressions of throughput are derived compared with the traditional equivalent Gaussian distribution method, the effect of throughput on information rate and signal- to-noise ratio is studied, and the optimal information rate parameter R is also given. Analysis and simulation demonstrate that equivalent chi-square distribution method can be effectively applied to the research of cooperative communication systems with the collaborative multiple relays.
