In a distributed space-time coding scheme, based on the relay channel model, the relay nodes co-operate to linearly process the transmitted signal from the source and forward them ...
Abstract— The “water-filling” solution for the quadratic ratedistortion function of a stationary Gaussian source is given in terms of its power spectrum. This formula natura...
In this paper, we extend our previous work onjoint source-channel coding to scalablevideo transmissionover wireless direct-sequence code-division-multiple-access(DS-CDMA)multipath...

Synchronization of relay nodes is an important and critical issue in exploiting cooperative diversity in wireless networks. In this paper, two asynchronous cooperative diversity s...
In this paper, we provide a new achievable ergodic secrecy rate region for the multiple access wiretap channel in fading. Our achievable scheme is based on repeating each symbol at...
