Journal ArticleDOI
Feedforward Carrier Recovery for Coherent Optical Communications
Ezra Ip,Joseph M. Kahn +1 more
TL;DR: In this paper, a carrier-synchronization scheme for coherent optical communications that uses a feed-forward architecture that can be implemented in digital hardware without a phase-locked loop is studied.
Journal ArticleDOI
Multiple-subcarrier modulation for non-directed wireless infrared communication
J.B. Carruthers,Joseph M. Kahn +1 more
TL;DR: It is found that MSM schemes can allow operation at higher data rates than single-carrier modulation schemes without equalization and can be more bandwidth-efficient and also can provide a simple and flexible method for multiple access to the channel.
Journal ArticleDOI
Digital Equalization of Chromatic Dispersion and Polarization Mode Dispersion
Ezra Ip,Joseph M. Kahn +1 more
TL;DR: In this paper, a fractionally spaced equalizer (FSE) was proposed for electronic compensation of chromatic dispersion and polarization-mode dispersion in a dually polarized (polarization-multiplexed) coherent optical communications system.
Journal ArticleDOI
Emerging challenges: Mobile networking for “Smart Dust”
TL;DR: This work reviews the key elements of the emergent technology of “Smart Dust” and outlines the research challenges they present to the mobile networking and systems community, which must provide coherent connectivity to large numbers of mobile network nodes co-located within a small volume.
Journal ArticleDOI
Spectral efficiency limits and modulation/detection techniques for DWDM systems
Joseph M. Kahn,Keang-Po Ho +1 more
TL;DR: In this paper, the spectral efficiency of DWDM transmission systems is compared in terms of their spectral efficiencies and signal-to-noise ratio requirements, assuming amplified spontaneous emission is the dominant noise source.
