N2 - By employing lens antenna array and selection network, the beamspace MIMO can significantly reduce the number of power consumption radio frequency (RF) chains in millimeter-wave (mmWave) massive MIMO systems. However, most existing studies ignored the high energy consumption problem in the beamspace MIMO systems, which resulted in an obvious loss of the achievable sum-rate. To solve this problem, in this paper, we propose a new overlapped subarray phase shifter (OSAPS) architecture with low complexity for mmWave massive MIMO systems, where the analog part is realized by a reduction of phase shifters and power combiners. Simulation results show that the proposed overlapped sub-array phase shifter selection network (OSAPSSN) based hybrid precoding can effectively achieve the satisfied sum-rate performance, and outperform the conventional schemes with regard to energy efficiency.
