Abstract :
A new batch processing constant modulus algorithm derived by conjugate gradient direction to minimize the constant modulus criterion (CG-BPCMA) is presented. This algorithm uses conjugate gradient direction to choose the search direction. Compared with BPCMA based the Newton direction, the new algorithm not only has lower complexity, but also can converge to the minima of the CM criterion quickly.
