Impact of mismatched statistics on correlated MIMO capacity
Many recent works that study the impact of spatial correlation on the performance of multi-input multi-output (MIMO) systems assume a separable (also known as the Kronecker) model...

A Monotonicity Principle for Information Theory
We establish a monotonicity principle for convex functions that enables high-level reasoning about capacity in information theory. Despite its simplicity, this single idea is rema...

Why does the Kronecker model result in misleading capacity estimates?
Many recent works that study the performance of multi-input multi-output (MIMO) systems in practice assume a Kronecker model where the variances of the channel entries, upon decom...

Numerical Performance Evaluation of impaired OFDM Links using Alamouti Space Time Coding
—In this paper we present an analytical approach to evaluate the M-QAM bit error rate (BER) as well as channel capacity of Alamouti space time coded OFDM systems in case of direc...

Capacity Estimation of Non-Synchronous Covert Channels
Capacity estimation is an important part of covert channel analysis. It measures the severity of a covert channel by estimating the maximum information rate attainable over it. Tr...
