The Constant Modulus Algorithm is an adaptive algorithm for selecting equalizer filter weights which attempts to correct for degradation in signal quality suffered by constant envelope signals eg.FM over an imperfect transmission channel. This report reviews and evaluates the standard CMA and several of its variant, which were designed to improve on its performance or extend its applicability. Two variants seem to significantly increase convergence rate and appear worthy of further study or implementation.
