One bit beamforming
WebOne solution is to use a low-resolution ADC to replace the full-precision ADC. In this paper, we propose a mixed LMS (Least Mean Square) receiver beamforming method for a millimeter-wave one-bit antenna array. We first use a grid-based approach to roughly estimate the DOA (Direction of Arrival) of the incoming signal. Web1) We propose downlink beamforming schemes for massive MIMO with 1-bit DACs based on the constructive inter-ferenceformulation.We firstly considera quantizedlinear beamformingscheme, where it is analytically proventhat, in the massive MIMO region, the optimality is achieved by employing a strict phase rotation due to the favourable

WebThe use of single-bit modulators, rather than multi-bit A/D converters, can greatly reduce the electronics inside a beamformer [1], [2]. In recent years, receive beamforming using single-bit modulation has received significant attention. In [2]-[5], system level architectures are proposed, analyzed, and simulated for single-bit beamformers.
