Low-Complexity Hybrid Beamforming for Massive MIMO Systems in Frequency-Selective Channels
Sohail Payami, Mathini Sellathurai, Konstantinos Nikitopoulos
Hybrid beamforming for frequency-selective channels is a challenging problem as the phase shifters provide the same phase shift to all of the subcarriers. The existing approaches s…

Hybrid Beamforming with Reduced Number of Phase Shifters for Massive MIMO Systems
Sohail Payami, Mir Ghoraishi, Mehrdad Dianati +1
In this paper, two novel hybrid beamforming methods are proposed to reduce the cost and power consumption of hybrid beamformers with subconnected phase shifter network structure in…
