Randomized Isometric Linear-Dispersion Space-Time Block Coding for the DF Relay Channel
This article presents a randomized linear-dispersion space-time block code for decode-andforward synchronous relays. The coding matrices are obtained as a set of columns (or rows)...

A frequency hopping spread spectrum transmission scheme for uncoordinated cognitive radios
One of the major challenges to cognitive radios is the synchronization of distributed radios onto the same spectrum white spaces which vary in time and space. In this paper, we pr...

Combining multiple models of computation for scheduling and allocation
Many applications include a variety off unctions from different domains. Therefore, they are best modeled with a combination of different modeling languages. For a sound design pr...
