Abstract :
The lp norm back propagation algorithm for perceptron based adaptive equalization is analyzed taking account of possible numerical problem encountered when p<1. Two methods are proposed to overcome the numerical problem. Computer simulations indicate that simultaneous improvement in convergence rate and bit-error-rate (BER) performance can be achieved by using p<2
