For wireless communication, channel diversity is an effective method to achieve reliable communication and improve the system performance. Now, diversity-multiplexing tradeoff is the usually used method to evaluate the performance of different channel diversity scheme. This method can only be adapt to the case of high SNR. Based on the statistics characteristics of channel diversity factor, from the point of a new view, for traditional channel diversity technologies a new performance research method is proposed, theory analysis and simulation results testified the validity of the new method.
