A Real-Time Implementation of the Mobile WiMAX ARQ and Physical Layer
(Springer, 2015)
[Abstract] This paper presents an innovative software-defined radio architecture for the real-time implementation of WiMAX transceivers. The architecture consists of commercially available field-programmable gate array and ...
QoS constrained power minimization in the multiple stream MIMO broadcast channel
(Elsevier, 2018-02)
[Abstract]: This work addresses the design of optimal linear transmit filters for the Multiple Input-Multiple Output (MIMO) Broadcast Channel (BC) when several spatial streams are allocated to each user. We further consider ...
QoS constrained power minimization in the MISO broadcast channel with imperfect CSI
(Elsevier, 2017-02)
[Abstract]: In this paper we consider the design of linear precoders and receivers in a Multiple-Input Single-Output (MISO) Broadcast Channel (BC). We aim to minimize the transmit power while meeting a set of per-user ...
Design of Linear Precoders for Correlated Sources in MIMO Multiple Access Channels
(Institute of Electrical and Electronics Engineers, 2018-12)
[Abstract]: This paper focuses on distributed linear precoding when users transmit correlated information over a fading multiple-input and multiple-output multiple access channel. The precoders are optimized in order to ...
Transmission of Spatio-Temporal Correlated Sources Over Fading Multiple Access Channels With DQLC Mappings
(Institute of Electrical and Electronics Engineers, 2019-08)
[Abstract]: The design of zero-delay Joint Source-Channel Coding (JSCC) schemes for the transmission of correlated information over fading Multiple Access Channels (MACs) is an interesting problem for many communication ...
Analog Transmission of Spatio-Temporal Correlated Sources Over MAC With Modulo Mappings
(Institute of Electrical and Electronics Engineers, 2018-05)
[Abstract]: Modulo mappings is an appealing scheme for the analog transmission of spatially correlated discrete-time analog source symbols over multiple access channels. In this letter, we show that the modulo mappings are ...
Lattice-Based Analog Mappings for Low-Latency Wireless Sensor Networks
(Institute of Electrical and Electronics Engineers, 2023-10-01)
[Abstract]: We consider the transmission of spatially correlated analog information in a wireless sensor network (WSN) through fading single-input and multiple-output (SIMO) multiple access channels (MACs) with low-latency ...
Deep Contextual Bandit and Reinforcement Learning for IRS-Assisted MU-MIMO Systems
(Institute of Electrical and Electronics Engineers, 2023-07)
[Abstract]: The combination of multiple-input multiple-output (MIMO) systems and intelligent reflecting surfaces (IRSs) is foreseen as a critical enabler of beyond 5G (B5G) and 6G. In this work, two different approaches ...
Alternating Minimization for Wideband Multiuser IRS-Aided MIMO Systems Under Imperfect CSI
(Institute of Electrical and Electronics Engineers, 2023-11-28)
[Abstract]: This work focuses on wideband intelligent reflecting surface (IRS)-aided multiuser MIMO systems. One of the major challenges of this scenario is the joint design of the frequency-dependent base station (BS) ...
Transmission of Analog Information Over the Multiple Access Relay Channel Using Zero-Delay Non-Linear Mappings
(Institute of Electrical and Electronics Engineers, 2019-04-04)
[Abstract]: We consider the zero-delay encoding of discrete-time analog information over the Multiple Access Relay Channel (MARC) using non-linear mapping functions. On the one hand, zero-delay non-linear mappings are ...
