Opportunistic beamforming exploits multi-user diversity by introducing a varying beamformer independent of the channel realizations.
Traditional routing in IP networks is along shortest paths using link weight as the metric.
In this paper we present new ideas to accelerate the computation of the eigenvector of the transition matrix associated to the PageRank algorithm.
Optical fibers constitute an attractive alternative to conventional wiring for the distribution of high spectral purity microwave signals.
We consider that the wireless terminals form a Poisson point process with support in a uniform or a fractal map.
This paper illustrates the relevance of specific allocation of flexible opto-electronic regeneration for ultimate spectral efficiency in the core elastic WDM networks: up to 2.5 times more traffic
Ethernet's move into metropolitan and wide area networks is driving a rapidly growing market opportunity.
Optimized second-harmonic generation (SHG) in Quantum Cascade (QC) lasers with specially designed active regions is reported.
Optimized second-harmonic generation (SHG) in Quantum Cascade (QC) lasers with specially designed active regions is reported.
We compared direct-detection optical-OFDM systems with QPSK, QAM 16 and QAM64 subcarrier modulation for increase of bitrate.
