Performance of MIMO systems in measured indoor channels with transmitter noise
(Springer, 2012)
This study analyzes the impact of transmitter noise on the performance of multiple-input multiple-output (MIMO) systems with linear and nonlinear receivers and precoders. We show that the performance of MIMO linear and ...
Transmission of Still Images Using Low-Complexity Analog Joint Source-Channel Coding
(M D P I AG, 2019-07-03)
[Abstract] An analog joint source-channel coding (JSCC) system designed for the transmission of still images is proposed and its performance is compared to that of two digital alternatives which differ in the source encoding ...
A MATLAB Interface for Analyzing Conformal Arrays Composed of Polarized Heterogeneous Elements
(Institute of Electrical and Electronics Engineers, 2011-10)
[Abstract] As an extension and improvement of a previous work, this paper presents a graphical interface designed with MATLAB®, which is capable of representing both the spatial and electrical configurations of a conformal ...
Time Modulated Arrays: from their Origin to Their Utilization in Wireless Communication Systems
(M D P I AG, 2017-03-14)
[Abstract] Time-modulated arrays (TMAs) are electromagnetic systems whose radiated power pattern is controlled by the application of variable-width periodical pulses to the individual elements. The nonlinear nature of the ...
Impact of Time-Modulated Arrays on the BER of Linear Digital Modulations
(Taylor & Francis, 2015-08-21)
[Abstract] Time modulation provides a simple way to control the power radiation pattern of an antenna array. By appropriately selecting the parameters of a Time-Modulated Array (TMA) it is possible to obtain a reconfigurable ...
JSCC-Cast: A Joint Source Channel Coding Video Encoding and Transmission System with Limited Digital Metadata
(MDPI, 2021)
[Abstract] This work considers the design and practical implementation of JSCC-Cast, a comprehensive analog video encoding and transmission system requiring a reduced amount of digital metadata. Suitable applications for ...
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, ...
Dual-Beam Steerable TMAs Combining AM and PM Switched Time-Modulation
(MDPI, 2022)
[Abstract] Wireless sensor networks (WSN) are increasingly requiring directional antennas that not only provide higher capacity, security, transmission range or robustness against interference, but also contribute with ...
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 ...
Bit Error Probability and Capacity Bound of OFDM Systems in Deterministic Doubly-Selective Channels
(Institute of Electrical and Electronics Engineers, 2020-10)
[Abstract]: Doubly-selective channels, such as those that occur when the transmitter and the receiver move relative to each other at high speeds, are a key scenario for fifth generation (5G) cellular systems, which are ...
