Noncooperative Eigencoding for MIMO Ad hoc Networks
A new noncooperative eigencoding algorithm is introduced for MIMO Ad hoc networks. The algorithm performs generalized waterfilling with respect to its transmit covariance matrix a...

Robust frequency synchronization for an OFDMA uplink system disturbed by a Cognitive Radio system interference
In Cognitive Radio (CR) systems, spectrum sensing plays a key role to determine the free frequency bands. However, when the primaryuser (PU) signal spectrum exhibits localized fad...

Clustering in cooperative networks
Abstract—Low power ad hoc wireless networks operate in conditions where channels are subject to fading. Cooperative diversity mitigates fading in these networks by establishing v...

Probabilistic Analysis of the Semidefinite Relaxation Detector in Digital Communications
We consider the problem of detecting a vector of symbols that is being transmitted over a fading multiple?input multiple?output (MIMO) channel, where each symbol is an ?th root of...
