sensor array and multichannel signal processing workshop
作者: Yimin D. Zhang Moeness G. Amin Center for Advanced Communications Villanova University Villanova PA USA
Compressive sensing (CS) has successfully been applied to reconstruct sparse signals and images from few observations. For multi-component nonstationary signals characterized by instantaneous frequency laws, the spars... 详细信息

sensor array and multichannel signal processing workshop
作者: Steven Kay Quan Ding Muralidhar Rangaswamy Department of Electrical Computer and Biomedical Engineering University of Rhode Island USA Air Force Research Laboratory USA
In detection theory, the optimal Neyman-Pearson rule applies when the characteristics of the signal and the noise are completely known. However, in many practical scenarios such as multipath or moving targets, only pa... 详细信息

sensor array and multichannel signal processing workshop
作者: Domenico Ciuonzo Gianmarco Romano Pierluigi Salvo Rossi Department of Information Engineering Second University of Naples Italy
We study channel-aware binary decision fusion over a Rayleigh flat fading shared channel with multiple antennas at the Decision Fusion Center (DFC). We derive the optimum and three sub-optimal fusion rules, namely the... 详细信息

sensor array and multichannel signal processing workshop
作者: M. Sharp M. Pekala J. Nanzer I-J. Wang D. Lucarelli K. Lauritzen Applied Physics Laboratory Johns Hopkins University USA
Beamformers are spatial filters that focus energy in a particular direction while attempting to eliminate interference from other directions. this paper compares several adaptive approaches that seek to provide detect... 详细信息

sensor array and multichannel signal processing workshop
作者: A. Aubry A. De Maio B. Jiang S. Zhang Università degli Studi di Napoli Federico II Napoli Italy Industrial and Systems Engineering University of Minnesota Minneapolis Minneapolis MN USA
In this paper, we propose a cognitive approach to design phase-only modulated waveforms sharing a desired ambiguity function. We formulate the problem as a quartic order polynomial optimization problem with a constant... 详细信息
