Online Calibration of Phase Shifter Network for mmWave Massive MIMO Systems in Multipath Channels
Published: Oct 1, 2019
Abstract
This paper develops a novel approach to the calibration of the phase shifter network (PSN) in millimeter wave (mmWave) massive multiple-input multiple-output (MIMO) communication systems under multipath channel scenarios. Specifically, we formulate the core phase deviation estimation problem in the calibration task as an optimization program with unimodular constraints. Efficient algorithms are then developed to estimate the phase deviations...
