A cost-effective IoT system for monitoring Indoor radon gas concentration
(M D P I AG, 2018-07-08)
[Abstract] Radon is a noble gas originating from the radioactive decay chain of uranium or thorium. Most radon emanates naturally from the soil and from some building materials, so it can be found in many places around the ...
On the Feasibility of Time-Modulated Arrays for Digital Linear Modulations: a Theoretical Analysis
(Institute of Electrical and Electronics Engineers, 2014)
[Abstract] Wireless communications are widely based on linear digital modulation methods, which introduce the digital baseband information in the amplitude and/or in the phase of a carrier sinusoid. Time-modulated arrays, ...
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 ...
Channel Covariance Identification in FDD Massive MIMO Systems
(IEEE, 2018-11)
[Abstract]: Many channel estimation methods in Massive MIMO FDD systems usually rely on the knowledge of the channel covariance matrix to operate. However, in real scenarios, this covariance is not known beforehand, and ...
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 ...
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 ...
