Interference Alignment Testbeds
(Institute of Electrical and Electronics Engineers, 2017)
[Abstract]: Interference alignment has triggered high impact research in wireless communications since it was proposed nearly 10 years ago. However, the vast majority of research is centered on the theory of interference ...
Time-Modulated Arrays Controlled With Sinusoidal Pulsewidth Modulation
(Institute of Electrical and Electronics Engineers, 2020)
[Abstract]: In this letter, sinusoidal pulsewidth modulation (PWM) is applied to the design of time-modulated arrays (TMAs). The array excitations are modulated using PWM-synthesized sine waveforms. This provides increased ...
Dual-Signal Transmission Using RF Precoding and Analog Beamforming With TMAs
(Institute of Electrical and Electronics Engineers, 2018)
[Abstract]: Time-modulated arrays (TMAs) receiving beamforming provide a noteworthy hardware simplicity given the ability of this multi-antenna technique to transform spatial diversity into frequency diversity. However, ...
Experimental evaluation in wireless communications
(SpringerOpen & European Association for Signal Processing, 2017)
[Abstract]: This editorial sums up relevant topics on the assessment of wireless communication systems covered by the especial issue entitled “Experimental Evaluation in Wireless Communications.” The topics include practical ...
Experimental evaluation of interference alignment for broadband WLAN systems
(SpringerOpen & European Association for Signal Processing, 2015)
[Abstract]: In this paper, we present an experimental study on the performance of spatial interference alignment (IA) in indoor wireless local area network scenarios that use orthogonal frequency division multiplexing ...
Performance Analysis of Time-Modulated Arrays for the Angle Diversity Reception of Digital Linear Modulated Signals
(Institute of Electrical and Electronics Engineers, 2017)
[Abstract]: Diversity occurs whenever several copies of the same transmitted signal arrive at a receiver. Such a situation allows for improving the performance of a wireless communication system transmitting over a radio ...
Emulating extreme velocities of mobile LTE receivers in the downlink
(SpringerOpen & European Association for Signal Processing, 2015)
[Abstract]: Long-Term Evolution (LTE) is expected to substitute the Global System for Mobile (GSM) Communications as the radio access technology for railway communications. Recently, considerable attention has been devoted ...
An IoT system for a smart campus: Challenges and solutions illustrated over several real-world use cases
(Elsevier, 2024-04)
[Abstract]: This article discusses the development of an IoT system for monitoring and controlling various devices and systems from different vendors. The authors considered key challenges in IoT projects, such as ...
Analogue joint source-channel coding for multiple input multiple output–orthogonal frequency division multiplexing systems
(Wiley, 2016)
[Abstract]: Analogue joint source-channel coding (JSCC) has been shown to approach the optimal distortion-cost trade-off when transmitting over additive white Gaussian noise channels. In this work, we consider analogue ...
Analog joint source-channel coding over MIMO channels
(SpringerOpen & European Association for Signal Processing, 2014-02)
[Abstract]: Analog joint source-channel coding (JSCC) is a communication strategy that does not follow the separation principle of conventional digital systems but has been shown to approach the optimal distortion-cost ...
