Combined single-mode/multimode fiber link supporting simplified in-building 60-GHz gigabit wireless access

Pham, Tien-Thang; Lebedev, Alexander; Beltrán, Marta; Yu, Xianbin; Llorente Sáez, Roberto; Monroy, Idelfonso Tafur (Elsevier, 2012-07)

In this paper, we propose and experimentally demonstrate a simple, cost-effective hybrid gigabit fiber-wireless system for in-building wireless access. Simplicity and cost-effectiveness are achieved in all parts of the ...
Dual Photonic Generation Ultrawideband Impulse Radio by Frequency Shifting in Remote-Connectivity Fiber

Beltrán Ramírez, Marta; Llorente Sáez, Roberto (Institute of Electrical and Electronics Engineers (IEEE), 2011)

[EN] An impulse-radio ultrawideband (UWB) photonic generation technique based on frequency shifting in the remote connectivity fiber in optical access networks is proposed and analyzed in this paper. This technique is based ...
Experimental analysis of 60-GHz VCSEL and ECL photonic generation and transmission of impulse-radio Ultra-Wideband signals

Beltrán Ramírez, Marta; Jensen, Jesper Bevensee; Llorente Sáez, Roberto; Monroy, Idelfonso Tafur (Institute of Electrical and Electronics Engineers (IEEE), 2011-08-01)

[EN] Optical generation of impulse-radio ultra-wideband (UWB) signals in the 60-GHz band is proposed and experimentally demonstrated. External-cavity laser (ECL) and vertical-cavity surface-emitting laser (VCSEL) is employed ...
Fiber Wireless Transmission of 8.3-Gb/s/ch QPSK-OFDM Signals in 75-110-GHz Band

Deng, Lei; Beltrán Ramírez, Marta; Pang, Xiaodan; Zhang, Xu; Arlunno, Valeria; Zhao, Ying; Caballero, Antonio; Dogadaev, Anton; Yu, Xianbin; Llorente Sáez, Roberto; Liu, Deming; Monroy, Idelfonso Tafur (Institute of Electrical and Electronics Engineers (IEEE), 2012-03)

[EN] In this letter, we present a scalable high-speed W-band (75-110-GHz) fiber wireless communication system. By using an optical frequency comb generator, three-channel 8.3-Gb/s/ch optical orthogonal frequency-division ...
Performance Comparison of OFDM-UWB Radio Signals Distribution in Long-Reach PONs Using Mach-Zehnder and Linearized Modulators

Alves, Tiago; Morant, Maria; Cartaxo, Adolfo; Llorente, Roberto (Institute of Electrical and Electronics Engineers (IEEE), 2011-06)

[EN] The performance of orthogonal frequency division multiplexing ultra wideband (UWB) radio signals distribution in long-reach passive optical networks (LR-PONs) using conventional chirp-less Mach Zehnder (MZ) and ...
Performance of a 60-GHz DCM-OFDM and BPSK-Impulse ultra-wideband system with radio-over-fiber and wireless transmission employing a directly-modulated VCSEL

Beltrán, Marta; Jensen, Jesper Bevensee; Yu, Xianbin; Llorente, Roberto; Rodes, Roberto; Ortsiefer, Markus; Neumeyr, Christian; Monroy, Idelfonso Tafur (Institute of Electrical and Electronics Engineers (IEEE), 2011-06-06)

[EN] The performance of radio-over-fiber optical transmission employing vertical-cavity surface-emitting lasers (VCSELs), and further wireless transmission, of the two major ultra-wideband (UWB) implementations is reported ...
