Abstract :
In this paper, we discussed several kinds of nonlinear filters. In the end, inspired by these filters, a new kind of nonlinear filter called nonlinear LTJ filter was proposed. We discussed their SNR improvement and convergence speed in narrow band interference suppression in DS-SS communications and their complexity
