White Space Regions
We study a classical problem in communication and wireless networks called Finding White Space Regions. In this problem, we are given a set of antennas (points) some of which are noisy (black) and the rest are working fine (white). The goal is to find a set of convex hulls with maximum total area that cover all white points and exclude all black points. In other words, these convex hulls make i...
متن کاملIndoor White Space Network Design
of thesis entitled: Indoor White Space Network Design Submitted by ZHANG, Jincheng for the degree of Master of Philosophy at The Chinese University of Hong Kong in July 2014 The Federal Communications Commission (FCC) released the final rule to approve of TV white spaces (TVWS), i.e., locally vacant TV channels, for unlicensed use in 2010. This TV spectrum will mitigate the shortage of wireless...
متن کاملLinear State Space Theory in the White Noise Space Setting
We study state space equations within the white noise space setting. A commutative ring of power series in a countable number of variables plays an important role. Transfer functions are rational functions with coefficients in this commutative ring, and are characterized in a number of ways. A major feature in our approach is the observation that key characteristics of a linear, time invariant,...
متن کاملOptimal space coverage with white convex polygons
Assume that we are given a set of points some of which are black and the rest are white. The goal is to find a set of convex polygons with maximum total area that cover all white points and exclude all black points. We study the problem on three different settings (based on overlapping between different convex polygons): (1) In case convex polygons are permitted to have common area, we present ...
