In this paper, we investigate a transmitter and receiver design for a single-user massive SIMO (single-input multiple-output) system with 1-bit analog-to-digital converters (ADCs) at the base station (BS), where the user adopts higher-order modulatio

By sharing common assets such as the power grid, prosumers are closely interrelated by their actions and interests. Game theory provides powerful tools for increased coordination among the prosumers to optimize the energy resources. However, dependin

We consider multi-group multicast precoding designs for cell-free massive multiple-input multiple-output (MIMO) systems. To optimize the transmit and receive beamforming strategies, we focus on minimizing the sum of the maximum mean squared errors (M

This paper presents an analytical framework for the data detection in massive multiple-input multiple-output uplink systems with 1-bit analog-to-digital converters (ADCs). Considering the single-user case, we provide closed-form expressions of the ex

We present an analytical framework for the channel estimation and the data detection in massive multiple-input multiple-output uplink systems with 1-bit analog-to-digital converters (ADCs) and i.i.d. Rayleigh fading. First, we provide closed-form exp

Most works on cell-free massive multiple-input multiple-output (MIMO) consider non-cooperative precoding strategies at the base stations (BSs) to avoid extensive channel state information (CSI) exchange via backhaul signaling. However, considerable p

This paper tackles the problem of downlink data transmission in massive multiple-input multiple-output (MIMO) systems where user equipments (UEs) exhibit high spatial correlation and channel estimation is limited by strong pilot contamination. Signal

Ultra-Reliable Low-Latency Communications (URLLC) was introduced into 5G networks to facilitate machine to machine communication for such applications as the Internet of Things. But designing URLLC systems, with disjointed treatment of the topic in t

We propose a distributed precoding design for downlink cell-free massive multiple-input multiple-output (MIMO) systems where the channel state information (CSI) exchange via backhaul signaling is entirely replaced by a novel over-the- air (OTA) signa

The majority of works on cell-free massive multiple-input multiple-output (MIMO) adopt uncoordinated transmit/receive strategies at the base stations (BSs) to avoid extensive channel state information (CSI) exchange via backhaul signaling. However, s
