Expectation Maximization Aided Modified Weighted Sequential Energy Detector for Distributed Cooperative Spectrum Sensing
In this paper, we propose a modified WSED (mWSED) that uses the primary user states information over the window to aggregate only the highly correlated energy samples in its test statistic.
High Accuracy Distributed Kalman Filtering for Frequency and Phase Synchronization in Distributed Phased Arrays
Precise frequency and phase synchronization are among the important aspects in a coherent distributed phased array antenna system, and are among the most challenging to achieve for microwave frequencies and above.
Motion Classification Based on Harmonic Micro-Doppler Signatures Using a Convolutional Neural Network
We demonstrate the classification of common motions of held objects using the harmonic micro-Doppler signatures scattered from harmonic radio-frequency tags.
Design of a Single-Element Dynamic Antenna for Secure Wireless Applications
The dynamic antenna supports a constantly changing current distribution that generates a radiation pattern that is static in a desired direction and dynamic elsewhere, thereby imparting additional modulation on the signal and obscuring information transmitted or received outside of the secure spatial region.
Online Expectation-Maximization Based Frequency and Phase Consensus in Distributed Phased Arrays
In this paper, we propose a push-sum based frequency and phase consensus (PsFPC) algorithm for the directed networks.
Wireless Picosecond Time Synchronization for Distributed Antenna Arrays
Distributed antenna arrays have been proposed for many applications ranging from space-based observatories to automated vehicles.
A Message Passing Based Average Consensus Algorithm for Decentralized Frequency and Phase Synchronization in Distributed Phased Arrays
We consider the problem of decentralized frequency and phase synchronization in distributed phased arrays via local broadcast of the node electrical states.
Frequency and Phase Synchronization in Distributed Antenna Arrays Based on Consensus Averaging and Kalman Filtering
Simulation results show that upon convergence the DFPC algorithm can align the frequencies and phases of all the nodes up to a residual phase error that is governed by the oscillators and the estimation errors.
Distortion Mitigation in Millimeter-Wave Interferometric Radar Angular Velocity Estimation Using Signal Response Decomposition
