Maximization of the weighted sum-rate of secondary users (SUs) possibly equipped with
multiantenna transmitters and receivers is considered in the context of cognitive radio (CR) …

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 …

The cloud radio access network (C-RAN) is a promising architecture for future radio access
networks (RANs) due to its advantages in cost efficiency, flexibility, and utilization efficiency …

Consider the max-min fairness linear transceiver design problem for a multi-user multi-input
multi-output (MIMO) interference channel. When the channel knowledge is perfectly known …

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

In multiple-input multiple-output (MIMO) systems, power constraints are critically important
for transceiver designs. The most popular and widely used power constraint is sum power …

We consider the precoding problem in an amplify-and-forward (AF) multiple-input-multiple-
output (MIMO) relay system in which multiple antennas are equipped at the source, the …

In this paper, we study an optimal transmit strategy for multiple-input single-output (MISO)
Gaussian channels with joint sum and per-antenna power constraints. We study in detail the …

This paper considers a downlink unicast transmission in a multicell network with multiple
users. In a network with frequency reuse factor of one, intercell interference is a limiting …

We address the problem of the downlink beamformer design for signal-to-interference-plus-
noise ratio balancing in a multiuser multicell environment with imperfectly estimated …
