Abstract

In this paper, we consider an uplink multiuser hybrid beamforming system where an access point (AP) communicates with multiple stations (STAs) simultaneously. The performance of the uplink multiuser hybrid beamforming system depends on the effective channel which is given by the product of channel matrix and the analog beams. Therefore, to maximize the performance, we need to select the appropriate analog beams from the set of predefined analog beams. In this paper, we propose a low complexity analog beam selection algorithm for the uplink multiuser hybrid beamforming system. Additionally, we compare the complexity to show that the proposed analog beam selection algorithm has much less complexity than the exhaustive search based optimum analog beam selection while the performance loss of the proposed analog beam selection algorithm is not significant compared to the optimum analog beam selection, which is shown by the numerical results.
