✦ Synopsis
A common assumption in blind equalization schemes using the Constant Modulus Algorithm (CMA) is that the source sequence is an independent identically distributed (i.i.d.) sequence with equiprobable symbols. Much of the analysis demonstrating the global convergence of CMA in a noiseless channel to an openeye setting uses this assumption. This work investigates the e ect of source statistics (distributions and correlations) on the location of CMA stationary points in the fractionally sampled equalizer case under the conditions of equalizability. The work identiÿes the stationary points as the solution set of a system of multivariate polynomial equations with monomial coe cients given by the source moments. ?
