Abstract :
Several models of wide-band broadcast communication scenarios are studied with an emphasis on conditions under which, as the bandwidth tends to infinity, time sharing is asymptotically optimal. The models include the Gaussian channel, the Poisson channel, the "very noisy" channel, and the average-power limited fading channel. Only stochastically degraded scenarios are studied.
