Total Power Minimization: Joint Antenna Selection and Beamforming Design

In this paper, we consider the total power minimization problem when we have signal-to-interference-plus-noise ratio (SINR) constraints. The consumed power in the circuits depends on the number of active antennas, which can be modeled using zero-norm. Due to the difficulty of dealing with the non-convex zero-norm, we used the standard alternate weighted one-norm approach. We addressed the total power minimization for a narrowband system with and without perantenna power constraints (PAPCs). We derived iterative closed-form expressions in both cases. Then we analysed the case when we have multiple bands operating at the same time. Analogous closed-form expressions are provided. Our simulation results show that significant gains can be obtained in terms of the total power required compared to standard methods that do not take into account the circuit power.
