  Abstract

CMA(Constant Modulus Algorithm) is a kind of blind channel equalization that it must determine step-size beforehand. But it is unable to fix in different channel situations frequently because it should never be corrected by the wayside once it decided. In this paper we propose a new variable step size CMA Algorithm. To achieve this we propose new CMA cost function and use average of its gradient.
