Experimental Characterization of LTE Wireless Links in High-Speed Trains
(Hindawi, 2017)
[Abstract]: Multimedia and data-based services experienced a nonstopping growth over the last few years. People are continuously on the move using devices to access multimedia contents or other data-based services. Due to ...
Enhanced Time-Modulated Arrays for Harmonic Beamforming
(Institute of Electrical and Electronics Engineers, 2017)
[Abstract]: One of the primary features of time-modulated arrays (TMAs) is their ability to adapt their harmonic patterns to exploit the angular diversity of multipath wireless channels. In such a case, the TMA excitations ...
Propagation modeling for outdoor-to-indoor and indoor-to-indoor wireless links in high-speed train
(Elsevier, 2017)
[Abstract]: Nowadays telecommunication companies have shown a great interest in deploying broadband mobile wireless networks in high-speed trains (HSTs) with the aim of supporting both passenger services provisioning as ...
Measurement-Based Characterization of Train-to-Infrastructure 2.6 GHz Propagation Channel in a Modern Subway Station
(Institute of Electrical and Electronics Engineers, 2018)
[Abstract]: Channel characterization is essential when planning wireless communication deployments. We consider the wireless channel characterization in a modern subway station and its corresponding entrance tunnel, a topic ...
Multibeam Single-Sideband Time-Modulated Arrays
(Institute of Electrical and Electronics Engineers, 2020)
[Abstract]: The design of efficient time-modulated arrays (TMAs) for multi-beam steering purposes must be based on both a type of periodical sequences that guarantees an adequate windowing of exploited harmonics, and a ...
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 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 ...
