—Cooperative spectrum sensing has been shown to greatly improve the sensing performance in cognitive radio networks. However, if the cognitive users belong to different service p...
Abstract—In this contribution we present a numerical approach to evaluate the bit error rate and mutual information of OFDM links affected by transmitter nonlinearities, phase no...
—In this paper, we propose a novel channel estimation scheme for the broadcast phase of the newly invented twoway relaying technique. Instead of using pilot sequences, we exploit...

—We present a blind turbo equalizer for QAM signals that exploits the statistics that a channel code imposes on the transmitted signal. The receiver is an adaptation of previous ...
Digital storage demand is growing with the increasing use of digital artifacts from media files to business documents. Regulatory frameworks ask for unaltered, durable storage of...
