Abstract :
This paper presents a new approach for channel equalization using a multiplier-free adaptive algorithm. The algorithm is based on a quantized version of the Euclidean direction search method of optimization. The algorithm yields filter coefficients that are powers of 2, so that multiplications are reduced to simple shifts. The update equation for the coefficients is also multiplier-free. Computer simulations are given to illustrate the performance of the algorithm.
