This research is receiving diversity wireless communication.Due to the condition of wireless communication is bad,can cause the distortion and introduce all kinds of jamming.In order to make full use of the multipath signal transmission of energy,in order to improve the reliability and receive transmission diversity is commonly overcome multipath fading of the wireless communication technology.Receiving diversity technology is simple,easy to achieve,but can obviously improve the multipath fading channel of transmission and reliability.
Wireless communications technology including receiving diversity,spatial diversity (including antenna beam diversity,diversity,polarization diversity,etc.),frequency diversity,time diversity and beam diversity,etc.Diversity of merger algorithm including receiving consolidation (SC),selectivity,etc) and EGC (gain mergers are warning) algorithm (etc.
Based on relevant theories of diversity,and analysis of performance of the algorithm simulation analysis.Simulation results show that the technique can effectively smooth diversity receiving multipath fading of SNR,Three kinds of merger algorithm are the best performance,such as diversity gain merger,selective merge the worst.
