Given an arc-weighted directed graph G=(V,A) and a pair of nodes s,t, we seek to find an s-t walk of length at most B that maximizes some given function f of the set of nodes visited by the walk.
Cellular transmission standards such as GSM and IS-54 produce data streams with varying degrees of significance at the source encoder level.
Faster-than-Nyquist signaling originally proposed by J. E.
Faster-than-Nyquist signaling promises higher spectral efficiency by introducing controlled intersymbol interference at the transmitter at the cost of a higher receiver complexity.
Upcoming fifth generation (5G) cellular networks will demand more from the physical layer (PHY) than current generation Orthogonal Frequency Division Multiplexing (OFDM) can deliver.
UF-OFDM is a promising 5G waveform candidate, close to CP-OFDM, but with better spectral properties. Efficient receiver implementations exist, which are close to CP-OFDM in terms of complexity.
We consider networks where traffic is served according to the Generalised Processor Sharing (GPS) principle.
We present a novel reduced-power channel reuse scheme to improve spectrum efficiency in wireless packet cellular networks.
Mobile networks are expected to serve a wide range of verticals, however the Long Term Evolution (LTE) network is optimized for basic mobile operator services only.
Today's workflow systems assume that each work item is executed by a single worker.
