Abstract
Car in interface multichannel car networking communication system,because of the self-organizing characteristics of vehicles and the imbalance of the road network grid,the frequency electronic jamming is produced,electronic interference filter can improve more car communication channel balance,reduce the bit error rate. Traditional methods using adaptive notch method with frequency electrical interference cancellation,cannot under the carrier frequency of the mutation to eliminate the frequency electronic interference,lead to poor performance. In this paper,a multiple vehicle communication system based on adaptive line enhances the same frequency electronic interference elimination method. First multiple vehicle communication system is built,the design is more communication channel allocation algorithm and carried out on the same frequency jamming signal modeling,the adaptive line enhancement,the implementation of same frequency electronic interference suppression,multiple vehicle communication system for the same frequency electronic interference elimination of optimization. Simulation experimental results show that the frequency electronic interference elimination suppression processing after the power spectrum of convergence to near the true frequency of signal,multiple vehicle communication signals can be effectively detected from the background noise,reduces the error rate of multiple vehicle communication system,shows the good channel equalization and improve ability,superior performance.关键词
