Wireless channel of monitoring the outdoor environment is very complex,and gets impacted by many factors such as multipath fading and noise,which deteriorates awfully the quality of signal reception.Further research on fading channel is helpful for receiving better signal and improving system performance.The factors of impacting fading channel were analyzed in detail,and the transmitting performance with fading channel was researched.The impact of fading channel on the probability of system detection was simulated,and the multi-bit local decisions in decision fusion with fading channel were researched.The simulation results suggest that the probability of system detection is lower compared to non-fading channel,and the sensor transmitting a bit decision is optimal.
