Channel Estimation and Transmission Strategy for Hybrid MmWave NOMA Systems
IEEE Journal of Selected Topics in Signal Processing(2019)
摘要
This paper presents a novel channel estimation and transmission strategy for millimeter wave (mmWave) non-orthogonal multiple access communication system with hybrid architecture. We first propose a general iterative index detection-based channel estimation algorithm that can obtain both direction of arrival and channel gain of each channel path. We then design an enhanced hybrid precoding scheme ...
