DOI: 10.1109/lwc.2018.2870360
Abstract: In this letter, we investigate channel estimation for wideband millimeter-wave (mmWave) massive multiple-input multiple-output under hybrid architecture with low-precision analog-to-digital converters (ADCs). To design channel estimation for the hybrid structure, both analog processing components and… read more here.
