Low-Complexity Constrained Constant Modulus SG-based Beamforming Algorithms with Variable Step Size
Lei Wang, Yunlong Cai, Rodrigo C. de Lamare
In this paper, two low-complexity adaptive step size algorithms are investigated for blind adaptive beamforming. Both of them are used in a stochastic gradient (SG) algorithm, whic…

Set-Membership Conjugate Gradient Constrained Adaptive Filtering Algorithm for Beamforming
Lei Wang, Rodrigo C. de Lamare
We introduce a new linearly constrained minimum variance (LCMV) beamformer that combines the set-membership (SM) technique with the conjugate gradient (CG) method, and develop a lo…

Set-Membership Constrained Conjugate Gradient Beamforming Algorithms
L. Wang, R. C. de Lamare
In this work a constrained adaptive filtering strategy based on conjugate gradient (CG) and set-membership (SM) techniques is presented for adaptive beamforming. A constraint on th…
