Abstract
A receiver, comprising an adaptive filter, performs blind equalization using a joint constant modulus algorithm—multimodulus algorithm (CMA-MMA) blind equalization algorithm. The adaptive filter is a two-filter structure. The receiver performs CMA-MMA blind equalization using asymmetric algorithms. This joint CMA-MMA blind equalization technique reduces the rate of occurrence of a diagonal solution.
