Abstract

The recent studies on hybrid beamformers with a combination of switches and phase shifters indicate that such methods can reduce the cost and power consumption of massive multiple-input multiple-output (MIMO) systems. However, most of the works have focused on the scenarios with frequency-flat channel models. This letter proposes an effective approach for such systems in frequency-selective channels and presents the closedform expressions of the beamformer and the corresponding sumrates. Compared to the traditional subconnected structures, our approach with a significantly smaller number of phase shifters results in a promising performance.
