Performance analysis of analog IF over fiber fronthaul link with 4G and 5G coexistence
Amol Delmade,Colm Browning,Arman Farhang,Nicola Marchetti,Linda Doyle,R. David Koilpillai,Liam P. Barry,Deepa Venkitesh +7 more
TL;DR: For the first time, to the best of the knowledge, the fronthaul network for providing simultaneous 4G and 5G services by propagating LTE signals in coexistence with UF-OFDM is demonstrated.
Journal ArticleDOI
Optical Heterodyne Analog Radio-Over-Fiber Link for Millimeter-Wave Wireless Systems
Amol Delmade,Colm Browning,Theo Verolet,Julien Poette,Arman Farhang,Hamza Hallak Elwan,R. David Koilpillai,Guy Aubin,F. Lelarge,Abderrahim Ramdane,Deepa Venkitesh,Liam P. Barry +11 more
TL;DR: In this article, three different techniques for the compensation of the laser frequency offset (FO) and phase noise (PN) in an optical heterodyne analog radio-over-fiber (A-RoF) system are presented.
Proceedings ArticleDOI
SAIC receiver algorithms for VAMOS downlink transmission
TL;DR: Voice services over Adaptive Multiuser channel in One Slot (VAMOS) performance in the presence of GMSK interferer is presented and WL metric is proposed which incorporates error covariance between I/Q components in the metric computation.
Proceedings ArticleDOI
OFDM Baud Rate Limitations in an Optical Heterodyne Analog Fronthaul Link using Unlocked Fibre Lasers
TL;DR: In this article, the effect of subcarrier baud rate and frequency offset variations on the performance of a 60 GHz OFDM signal generated using unlocked fiber lasers was analyzed in a 25 km mm-wave A-RoF heterodyne system.
Journal ArticleDOI
Polarization-Insensitive Phase Conjugation of QPSK Signal Using Bragg-Scattering FWM in SOA
TL;DR: In this paper, the authors demonstrate phase conjugate generation of 10 GBd PM-QPSK signal, simultaneously in both input and output ports of the SOA, with a penalty of < 1.5 dB.
