S. T. Abraha,Chigo Okonkwo,Hejie Yang,D. Visani,Y Yan Shi,Hyun-Do Jung,Eduward Tangdiongga,Ton Koonen +7 more
TL;DR: In this paper, a simple pulse design technique with a high fractional bandwidth was proposed for impulse radio ultrawideband (UWB) over fiber using a linear combination of the first-order Gaussian derivatives with different pulse-shaping factors.
Journal ArticleDOI
Wired and wireless multi-service transmission over 1mm-core GI-POF for in-home networks
D. Visani,Y Yan Shi,Chigo Okonkwo,Hejie Yang,van den Hpa Henrie Boom,Giovanni Tartarini,Eduward Tangdiongga,Amj Ton Koonen +7 more
TL;DR: Simultaneous transmission of broadband wired and wireless signals over 50 m 1mm-core GI-POF is demonstrated for the first time in this article, where 2.2 and 528 MHz 200Mbit/s UWB wireless signals are delivered with BER < 10−3 and EVM < 15.5%, respectively, in accordance with WiMedia standards.
