Abstract

This paper presents a new adaptive algorithm for solving the problem of joint antenna selection and beamform- ing in mobile communication systems. The proposed antenna selection technique is based on minimizing the co-channel interference, whereas the beamforming is carried out using a formulation of the minimum-variance distortionless-response (MVDR) criterion targeted to systems with a limited number of radio-frequency chains. Numerical simulation results corroborate the effectiveness of the proposed algorithm.
