Abstract:

aviation communication environment exists in the complex interference signal, strong interference on normal communication signals. The use of traditional algorithm for interference signal filtering, is inevitable because of the interference signal is too complex lead to inadequate filtration defects. For this, put forward a kind of optimization algorithm based on weighted residuals of aviation communication network in the complex interference filter method. The original signal frequency reduction processing, can eliminate the disturbance signal peak, improve the accuracy of the signal. Based on the related principle of weighted residual correction optimization algorithm, and residual optimization of communication signals, after processing the signal in the interference when zero trap formation, so as to realize the complex jamming signal filtering. Experimental results show that the algorithm presented in this paper for aviation communication network in the complex interference signal filtering, can effectively improve the accuracy of the filter, the effect is satisfactory.
