On some sufficient conditions for distributed Quality-of-Service support in wireless networks
Ashwin Ganesan
Given a wireless network where some pairs of communication links interfere with each other, we study sufficient conditions for determining whether a given set of minimum bandwidth…
On the Existence of Universally Decodable Matrices
Ashwin Ganesan, Pascal O. Vontobel
Universally decodable matrices (UDMs) can be used for coding purposes when transmitting over slow fading channels. These matrices are parameterized by positive integers and …
On Universally Decodable Matrices for Space-Time Coding
Pascal O. Vontobel, Ashwin Ganesan
The notion of universally decodable matrices (UDMs) was recently introduced by Tavildar and Viswanath while studying slow fading channels. It turns out that the problem of construc…
An Explicit Construction of Universally Decodable Matrices
Pascal O. Vontobel, Ashwin Ganesan
Universally decodable matrices can be used for coding purposes when transmitting over slow fading channels. These matrices are parameterized by positive integers and and a…
