【Abstract】 A new algorithm for adaptive interference rejection based on radial basis function network was analyzed. Compared with the conventional perceptron nerual network, its convergence rate is faster, and it is more robust to the circumstance change. The computer simulation results show that this kind of filter can reject narrowband interference efficiently and it is superior to other interference filter based on transversal filter or perceptron neural network.
