Compute-and-Forward on a Multi-User Multi-Relay Channel
Mohieddine El Soussi, Abdellatif Zaidi, Luc Vandendorpe
In this paper, we consider a system in which multiple users communicate with a destination with the help of multiple half-duplex relays. Based on the compute-and-forward scheme, ea…
Wideband Sensing and Optimization for Cognitive Radio Networks with Noise Variance Uncertainty
Tadilo Endeshaw Bogale, Luc Vandendorpe, Long Bao Le
This paper considers wide-band spectrum sensing and optimization for cognitive radio (CR) networks with noise variance uncertainty. It is assumed that the considered wide-band cont…
Joint Estimation of the Time Delay and the Clock Drift and Offset Using UWB signals
Achraf Mallat, Luc Vandendorpe
We consider two transceivers, the first with perfect clock and the second with imperfect clock. We investigate the joint estimation of the delay between the transceivers and the of…
Statistics of the MLE and Approximate Upper and Lower Bounds - Part 2: Threshold Computation and Optimal Signal Design
Achraf Mallat, Sinan Gezici, Davide Dardari +1
Threshold and ambiguity phenomena are studied in Part 1 of this work where approximations for the mean-squared-error (MSE) of the maximum likelihood estimator are proposed using th…
Statistics of the MLE and Approximate Upper and Lower Bounds - Part 1: Application to TOA Estimation
Achraf Mallat, Sinan Gezici, Davide Dardari +2
In nonlinear deterministic parameter estimation, the maximum likelihood estimator (MLE) is unable to attain the Cramer-Rao lower bound at low and medium signal-to-noise ratios (SNR…
Sensing Throughput Tradeoff for Cognitive Radio Networks with Noise Variance Uncertainty
Tadilo Endeshaw Bogale, Luc Vandendorpe, Long Bao Le
This paper proposes novel spectrum sensing algorithm, and examines the sensing throughput tradeoff for cognitive radio (CR) networks under noise variance uncertainty. It is assumed…
