Rotman lens-based two-tier hybrid beamforming for wideband mmWave MIMO-OFDM system with beam squint
Abstract In this paper, we study the hybrid beamforming for the wideband mmWave multiuser MIMO-OFDM system. We characterize the frequency-dependent beam angle problem, i.e., beam squint effect. Firstly, we extend the mmWave channel model from the Saleh-Valenzuela representation with the consideratio...
