An algorithm for adaptive blind equalization is proposed. It is interpreted as a sign version of a widely referenced algorithm for blind equalization, and it is demonstrated by way of simulations that the performance of this new sign algorithm is comparable to that of its unsigned version. A simple variable step-size scheme to accelerate the convergence process is also proposed. Simulation results are presented to demonstrate the significant improvements in the convergence rates that are obtained using this variable step-size scheme.>
