Abstract:
We propose two widely linear (WL) conjugate gradient-based (CG) beamforming algorithms, designed according to the minimum variance distortionless response (MVDR) criterion: the low-cost WL-CG (LC-WL-CG) and the low-cost WL modified CG (LC-WL-MCG) algorithms. Numerical results show that the proposed algorithms have an excellent performance at reduced computational cost.
