— In this paper, we concentrate on opportunistic scheduling for multicast information. We pose the problem as a multicast throughput optimization problem. As a solution we presen...
Let finite source and reproduction alphabets X and Y and a distortion measure d : X ? Y [0, ) be given. We study the minimum asymptotic rate required to describe a source distrib...
