Energy Efficiency Optimization for Millimeter Wave System with Resolution-Adaptive ADCs
Hualian Sheng, Xihan Chen, Xiongfei Zhai +2
This letter investigates the uplink of a multi-user millimeter wave (mmWave) system, where the base station (BS) is equipped with a massive multiple-input multiple-output (MIMO) ar…
Angular-Domain Selective Channel Tracking and Doppler Compensation for High-Mobility mmWave Massive MIMO
Guanying Liu, An Liu, Rui Zhang +1
In this paper, we consider a mmWave massive multiple-input multiple-output (MIMO) communication system with one static base station (BS) serving a fast-moving user, both equipped w…
Joint Frequency Reuse and Cache Optimization in Backhaul-Limited Small-Cell Wireless Networks
Wei Han, An Liu, Wei Yu +1
Caching at base stations (BSs) is a promising approach for supporting the tremendous traffic growth of content delivery over future small-cell wireless networks with limited backha…
Joint Channel Estimation and User Grouping for Massive MIMO Systems
Jisheng Dai, An Liu, Vincent K. N. Lau
This paper addresses the problem of joint downlink channel estimation and user grouping in massive multiple-input multiple-output (MIMO) systems, where the motivation comes from th…
Mixed-timescale Per-group Hybrid Precoding for Multiuser Massive MIMO Systems
Yinglei Teng, Min Wei, An Liu +2
Considering the expensive radio frequency (RF) chain, huge training overhead and feedback burden issues in massive MIMO, in this letter, we propose a mixed-timescale per-group hybr…
