On the base of cooperation diversity and receive diversity, this paper study a new diversity called dual-diversity that suit to use in uplink communication system. Firstly, it analyzed the work principle and the course of signal processing of the system that using receive Lacoste Polo Shirts diversity and cooperation diversity separately. Then analyzed the effectt that the two diversity technology using to improve the performance of communication Lacoste Shirts system by data analysis by MATLAB. Secondly, it introduced the communication system that used Cheap Lacoste Polo Shirts dual-diversity. It analyzed the impact of channel fading, the course of signal that re-transmit by the partnership and transmit by the resource received and combined by the antenna of the base. Finally, it analyzed the outage probability, SNR distributing and FER by data analysis using cheap nike shoes MATLAB, and summarized the effect of dual-diversity in improving the performance of the system.Theoretical and data analysis show that dual-diversity can improve the performance of uplink cheap Wholesale nike shoes communication system. But the change of channel capacity and diversity order and how it works in downlink system needs more work to do.
