Cramér-Rao Bound Optimization for Massive MIMO DFRC Systems with 1-Bit DACs and ADCs
Chenfei Huang, Mingjie Shao, Ya-Feng Liu
In this paper, we investigate the dual-function radar-communication (DFRC) design for massive multiple-input multiple-output (MIMO) systems equipped with 1-bit digital-to-analog co…
Downlink MIMO Channel Estimation from Bits: Recoverability and Algorithm
Rajesh Shrestha, Mingjie Shao, Mingyi Hong +2
In frequency division duplex (FDD) massive MIMO systems, a major challenge lies in acquiring the downlink channel state information}\ (CSI) at the base station (BS) from limited fe…
Extreme Point Pursuit -- Part II: Further Error Bound Analysis and Applications
Junbin Liu, Ya Liu, Wing-Kin Ma +2
In the first part of this study, a convex-constrained penalized formulation was studied for a class of constant modulus (CM) problems. In particular, the error bound techniques wer…
Extreme Point Pursuit -- Part I: A Framework for Constant Modulus Optimization
Junbin Liu, Ya Liu, Wing-Kin Ma +2
This study develops a framework for a class of constant modulus (CM) optimization problems, which covers binary constraints, discrete phase constraints, semi-orthogonal matrix cons…
One-Bit MIMO Detection: From Global Maximum-Likelihood Detector to Amplitude Retrieval Approach
Mingjie Shao, Wei-Kun Chen, Cheng-Yang Yu +2
As communication systems advance towards the future 6G era, the incorporation of large-scale antenna arrays in base stations (BSs) presents challenges such as increased hardware co…
