Capacity of Fading Broadcast Channels with Transmitter Ordering CSI
We derive the ergodic capacity region for a fading broadcast channel when the transmitter knows only the channel ordering information of the users and the receiver knows its transmitter-receiver channel gain and the ordering information at any time instant. We show that superposition coding based on the ordering information achieves the ergodic capacity region. Moreover, we prove that as the nu...
متن کاملA Partial Ordering Relation on Flat-Fading Channels
In this correspondence, we establish a partial ordering framework to compare flatfading channels in a capability sense, which is based on the relative dominance of their mutual information functions over a convex set of input distributions. For this purpose, we address the effect of the line-of-sight and scattering components on the mutual information of flat-fading channels. For example, we sh...
متن کاملThe analytic computability of the Shannon transform for a large class of random matrix channels
We define a class of “algebraic” random matrix channels for which one can generically compute the limiting Shannon transform using numerical techniques and often enumerate the low SNR series expansion coefficients in closed form. We describe this class, the coefficient enumeration techniques and compare theory with simulations.

متن کاملNast Nakagami: A Novel Stochastic Model for Cascaded Fading Channels
A generic and novel distribution, referred to as N∗Nakagami, constructed as the product of N statistically independent, but not necessarily identically distributed, Nakagamim random variables (RVs), is introduced and analyzed. The proposed distribution turns out to be a very convenient tool for modelling cascaded Nakagami-m fading channels and analyzing the performance of digital communications...
