Two-Stage Analog Combining in Hybrid Beamforming Systems with Low-Resolution ADCs.
IEEE Transactions on Signal Processing(2019)
摘要
In this paper, we investigate hybrid analog/digital beamforming for multiple-input multiple-output (MIMO) systems with low-resolution analog-to-digital converters for millimeter wave (mmWave) communications. In the receiver, we propose to split the analog combining subsystem into a channel gain aggregation stage followed by a spreading stage. Both stages use phase shifters. Our goal is to design t...
