  • Abstract
    A new mean-square-error automatic equalizer for synchronous data transmission is developed. It utilizes Rosen´s gradient-projection method to optimize parameters in the discrete frequency domain. The algorithm converges (in the mean) for any channel even in the presence of noise. It is shown that for the channels considered, convergence is faster (in a bounded sense) than for comparable time-domain equalizers.
