The energy spectral efficiency maximization (ESEM) problem of a multi-user, multi-relay,
multi-cell system is considered, where all the network nodes are equipped with multi …

For the next generation of wireless communication network, a heterogeneous network
architecture with macro cells, small cells, and relays offers numerous advantages, such as …

We first conceive a novel transmission protocol for a multi-relay multiple-input-multiple-
output orthogonal frequency-division multiple-access (MIMO-OFDMA) cellular network …

We present an approach to solve the nonconvex optimization problem that arises when
designing the transmit covariance matrices in multiuser multiple-input multiple-output …

In this paper, we investigate the interference alignment (IA) for the multiple-input-multiple-
output (MIMO) multicell downlink networks in the context of a square channel matrix. We …

This paper considers linear downlink transceiver design for the sum power minimization
problem with per-user rate constraints in a multi-cell multi-user MIMO system. This non …

In this article, we investigate the interference alignment (IA) solution for a K-user MIMO
interference channel. Proper users' precoders and decoders are designed through a desired …

This paper considers coordinated transmission for interference mitigation and power
allocation in a correlated two-user two-hop multi-input multioutput (MIMO) relay system. The …

Maximizing the total mutual information of multiuser multiple-input multiple-output (MIMO)
systems with interference is a challenging problem. In this paper, we consider the power …

A distributed approach is proposed to the problem of signal-to-interference-plus-noise-ratio
(SINR)-guaranteed power minimization (SGPM) for multicell multiuser (MCMU) multiple …
