A fast linear programming algorithm for blind equalization

A fast implementation of a special non-MSE cost function for blind equaliza tion is presented here. This baud-rate equalization algorithm is based on a convex cost function coupled with a simple linear constraint on the equali zer parameters. For a generic class of channels with persistently exciting quadrature amplitude modulation input signals, this new algorithm allows th e convergence of equalizer parameters to a unique global minimum achieving intersymbol interference suppression and carrier phase recovery.
