Joint User Scheduling and Resource Allocation for Millimeter Wave Systems Relying on Adaptive-Resolution ADCs
Xihan Chen, Yunlong Cai, An Liu +1
Millimeter wave (mmWave) communication systems using adaptive-resolution analog-to-digital converters (RADCs) have recently drawn considerable interests from the research community…
Power Control for Massive MIMO Systems with Nonorthogonal Pilots
Xihan Chen, Kaiming Shen, Hei Victor Cheng +3
This letter shows that optimizing the transmit powers along with optimally designed nonorthogonal pilots can significantly reduce pilot contamination and improve the overall throug…
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…
Two-Timescale Hybrid Compression and Forward for Massive MIMO Aided C-RAN
An Liu, Xihan Chen, Wei Yu +2
We consider the uplink of a cloud radio access network (C-RAN), where massive MIMO remote radio heads (RRHs) serve as relays between users and a centralized baseband unit (BBU). Al…
Technical Report: MIMO B-MAC Interference Network Optimization under Rate Constraints by Polite Water-filling and Duality
An Liu, Youjian, Liu +2
We take two new approaches to design efficient algorithms for transmitter optimization under rate constraints to guarantee the Quality of Service in general MIMO interference netwo…
