摘要

This paper presents a hybrid precoding processor for millimeter wave (mmWave) multiple-input-multiple-output (MIMO) communication systems. The proposed architecture supports 64 antennas with 4-to-8 RF chains, and 4-bit phase resolution for each phase shifter in the analog beamformer. A polar decomposition (PD) engine is designed to achieve a 2.4-to- $8.6\...
