Query: Low-Complexity Variable Forgetting Factor Constrained Constant Modulus
  RLS Algorithm for Adaptive Beamforming   In this paper, a recursive least squares (RLS) based blind adaptive
beamforming algorithm that features a new variable forgetting factor (VFF)
mechanism is presented. The beamformer is designed according to the constrained
constant modulus (CCM) criterion, and the proposed adaptive algorithm operates
in the generalized sidelobe canceler (GSC) structure. A detailed study of its
operating properties is carried out, including a convexity analysis and a mean
squared error (MSE) analysis of its steady-state behavior. The results of
numerical experiments demonstrate that the proposed VFF mechanism achieves a
superior learning and tracking performance compared to other VFF mechanisms.
