TECHNIQUE FOR IMPROVING THE BLIND CONVERGENCE OF AN ADAPTIVE EQUALIZER USING A TRANSITION ALGORITHM

摘要

The blind equalization technique uses both a constant modulus algorithm (CMA) and a multimodulus algorithm (MMA) during blind start-up. This approach forms the basis for a " transition algorithm ". One example of such a conversion algorithm is a CMA-MMA transition algorithm in which an adaptive filter is simply switched from CMA to MMA. As another example of the CMA-MMA conversion algorithm, rotation " CMA-MMA " transformation algorithm and a " dynamic rotation CMA-MMA " transformation algorithm.
