In this paper, we develop a unified framework for IRS-aided transceiver designs under
general power constraints in multiple-input multiple-output (MIMO) systems which implement …

This paper considers a multipair amplify-and-forward massive multipair multiple-input
multiple-output relaying system with one-bit analog-to-digital converters and one-bit digital …

The energy consumption of a base station (BS) has attracted much attention in the study of
wireless communication. Device-to-device communication, which can be utilized to offload …

Ambient backscatter devices (tags and readers) use existing radio frequency (RF) signals to
transmit data. Most prior works consider single-antenna tags, but this paper investigates the …

Matrix-monotonic optimization exploits the monotonic nature of positive semi-definite
matrices to derive optimal diagonalizable structures for the matrix variables of matrix …

In contrast to Part I of this treatise (Xing, 2021) that focuses on the optimization problems
associated with single matrix variables, in this paper, we investigate the application of the …

In this paper, throughput improvement of device-to-device (D2D)-aided underlaying cellular
networks is analyzed. The D2D devices are assumed to be capable of operating at the full …

Downlink precoding has been widely accepted as a crucial technique in low-earth-orbit
(LEO) satellite communications due to its advantages in improving the space division …

A popular technique of designing multiple-input multiple-output (MIMO) communication
systems relies on optimizing the positive semidefinite covariance matrix at the source. In this …

This paper investigates relay selection policies in a full-duplex (FD) based underlay
cooperative cognitive radio network. We consider a scenario consisting of multiple pairs of …
