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 ...
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 ...
Broadband Access in Complex Environments: LTE on Railway
(Institute of Electronics, Information and Communication Engineers, 2014)
[Abstract]: This paper assesses the main challenges associated with the propagation and channel modeling of broadband radio systems in a complex environment of high speed and metropolitan railways. These challenges comprise ...
Experimental evaluation of the WiMAX downlink physical layer in high-mobility scenarios
(SpringerOpen & European Association for Signal Processing, 2015)
[Abstract]: The experimental evaluation of the WiMAX downlink physical layer in high-mobility scenarios is extremely difficult to carry out because it requires the realization of measurement campaigns with expensive ...
Testbed-Assisted Learning for Digital Communications Courses
(John Wiley & Sons, 2013-09)
[Abstract] We introduce testbed-assisted learning as an effective means for teaching digital communications. Laboratory teaching activities of digital communications courses benefit very much from utilizing a hardware ...
Equalizers in mobile communications: Tutorial 38
(Institute of Electrical and Electronics Engineers & Instrumentation and Measurement Society, 2012-06)
[Abstract]: Modern cellular wireless systems would not be possible without high-performance equalizers. Signal impairments introduced by the wireless channel can only be compensated for by using such equalizers. This ...
