Cooperative MIMO Precoding with Distributed CSI: A Hierarchical Approach


The problem of network multiple-input multiple-output precoding under distributed channel state information is a notoriously challenging question, for which optimal solutions with reasonable complexity remain elusive. In this context, we assess the value of hierarchical information exchange, whereby an order is established among the transmitters (TXs) in such a way that~a given TX has access not only to its local channel estimate but also to the estimates available at the less informed TXs.

Two-Way Full-Duplex MIMO with Hybrid TX-RX MSE Minimization and Interference Cancellation


We consider a two-way full-duplex (FD) multiple-input multiple-output (MIMO) communication system in which devices are equipped both with multi-tap analog interference cancellers and TX-RX beamforming capabilities, and propose a joint analog and digital algorithm to simultaneously maximize the rate and minimize the self-interference (SI) in such a system.

FDD-based Cell-Free Massive MIMO Systems


Cell-free massive MIMO system is a promising technology of 5G wireless communications that provide a user-centric coverage to the user by the basestation cooperation. Most prior works on the cell-free massive MIMO systems assume the time division duplexing (TDD) systems, although the frequency division duplexing (FDD) systems dominate the current wireless communications. In the FDD systems, CSI acquisition and feedback overhead are serious concerns when the number of antennas is large.

Optimal Simultaneous Wireless Information and Power Transfer with Low-Complexity Receivers


Nowadays, a significant goal of technology is to prolong the lifetime of the wireless communication devices. To this end, this paper studies and optimizes the performance of simultaneous wireless information and power transfer with an integrated energy and information receiver, which has the advantage of low complexity and energy cost. Specifically, a tractable expression for the achievable rate is provided, which is then used to describe the achievable harvested energy-rate region.

Learning-Based Antenna Selection for Multicasting


In multi-antenna systems, it is preferred to activate only a subset of the available transmit antennas in order to save hardware and energy resources, without seriously degrading the system performance. However, antenna selection often poses very hard optimization problems. Joint multicast beamforming and antenna selection is one particular example, which is often approached by Semi-Definite Relaxation (SDR) type approximations. The drawback is that SDR lifts the problem to a much higher dimension, leading to considerably high memory and computational complexities.

Mirror-Prox SCA Algorithm for Multicast Beamforming and Antenna Selection


This paper considers the (NP-)hard problem of joint multicast beamforming and antenna selection. Prior work has focused on using Semi-Definite relaxation (SDR) techniques in an attempt to obtain a high-quality sub-optimal solution. However, SDR suffers from the drawback of having high computational complexity, as SDR lifts the problem to higher dimensional space, effectively squaring the number of variables.
