An Application of Sign-Error Constant Modulus Algorithm to Blind Adaptive Beamforming
Abstract: In the adaptive beamforming technology, the sign-error constant modulus (CM) algorithm is proposed based on Godard CM algorithm. The coefficient updating formulas are derived using the error of Godard CM algorithm. The advantage of this algorithm is that the multiplication is replaced by a sign change, and if step size is chosen as a negative power of 2, then the multiplication is replaced by a shifting operation that is easy and fast to implement. Computer simulations show that the sign-error CM algorithm has just a little faster convergence and better ability for acquisition and tracking of desired signal. Two CM algorithm are able to cancel interferences arriving from other than the look direction.
