Study of blind equalization techniques based on the variable step-size CMA

Blind equalization technique is one of the popular researching topics in the fields of digital communication nowadays, CMA is the basic algorithm of Bussgang series in blind equalization techniques. Because the step sizes effect on the capability of the CMA, the paper combines the variable step sizes algorithm, thus the new method come out which are blind equalization algorithm based on variable step-sizes. Simulation is done to evaluate their capability.
