Abstract
A blind equalization technique uses both the 'constant modulus algorithm' (CMA) and the 'multimodulus algorithm' (MMA) during blind start-up. This approach provides the basis for a 'transition algorithm.' One example of a transition algorithm is the CMA-MMA transition algorithm in which an adaptive filter simply switches from CMA to MMA. Other examples are variations of the CMA-MMA transition algorithm and are illustrated by the 'Constant Rotation CMA-MMA' transition algorithm and the 'Dynamic Rotation CMA-MMA' transition algorithm.
