In order to solve the problem of channel fading caused by multipath effect and communication interruption caused by occlusion of receiver in visible communication system, the diversity receiving technique was employed as the solution to improve communication quality. Considering the complexity of the receiver and the performance-cost ratio of the system implementation, the selective combination treatment which is relatively simple but also has the advantage of diversity was introduced at first. Secondly, after analyzing the number of branch selection combining mode, 4-road gate circuit was selected as diversity receiving signal processing circuit. Finally, the circuit simulation and physical testing was completed. The results show that the diversity receiving technique increases 10 dB signal to noise ration(SNR) of the receiver as compared with the receiving system without diversity circuit receiving device.
