Where H represents the hermitian transpose. The complex vector of weight adjust the amplitude and phase. The desired beam can be produced by adding together the MMSE weight adaptation with the steepest decent algorithm produces LMS algorithm[7]. For each new samples the weight vectors are updated, this process is called sample by sample techniques. Because of the successive correction the gradient vector leads to the MMSE. -Where H represents the hermitian transpose. The complex vector of weight　　adjust the amplitude and phase.
