Operational Capacity and Pseudoclassicality of a Quantum Channel
We explore some basic properties of coding theory of a general quantum communication channel and its operational capacity, including (1) adaptive measurement with feedback code, (...

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...

A Discrete Channel Model for Capturing Memory and Soft-Decision Information: A Capacity Study
A discrete (binary-input 2q -ary output) communication channel with memory is introduced with the objective to judiciously capture both the statistical memory and the soft-decision...

On the secrecy capacity of frequency-selective fading channels : A practical vandermonde precoding
We study the secrecy capacity of the frequency-selective wiretap channel. Assuming that a guard interval of L symbols is inserted to avoid the inter-block interference and these s...
