چکیده

We study the large deviations performance of consensus+innovations distributed detection under communication noise. We consider N agents, connected in a generic network; agents sense the environment and communicate over noisy links to detect the event of interest. The agents employ a consensus+innovations distributed detector, which operates as follows. At a time k, agent i first communicates its decision variable to its neighbors, and receives from neighbors their decision

Effect of Underwater Ambient Noise on Quadraphase Phase-shift Keying Acoustic Sensor Network Links in Extremely Low Frequency Band

This study evaluates the impact of underwater ambient noise using seven real noise samples; Dolphin, Rain, Ferry, Sonar, Bubbles, Lightning, and Outboard Motor in three frequency ranges in extremely low frequency (ELF) band. The ELF band is the most significant bandwidth for underwater long-range communication. ELF band which is extended from 3 to 3000 Hz clearly, faces bandwidth limitation. Me...

Large deviations analysis of consensus+innovations detection in random networks

We study the large deviations performance of consensus+innovations distributed detection over random networks, where each sensor, at each time k, weight averages its decision variable with its neighbors decision variables (consensus), and accounts for its new observation (innovation). Sensor observations are independent identically distributed (i.i.d.) both in time and space, but have generic (...

Heterodyne Binary . . Dpsk Systems Chris

This thesis describes an investigation of the perfomlance of binary differential phase shift keying (DPSK) modulation in an optical heterodyne communication system when both laser phase noise and shot noise are present. The laser phase noise is modelled as a Brownian motion process while the shot noise is modelled by additive white Gaussian noise. Four different receiver structures are consider...

A-New-Closed-form-Mathematical-Approach-to-Achieve Minimum Phase Noise in Frequency Synthesizers

The aim of this paper is to minimize output phase noise for the pure signal synthesis in the frequency synthesizers. For this purpose, first, an exact mathematical model of phase locked loop (PLL) based frequency synthesizer is described and analyzed. Then, an exact closed-form formula in terms of synthesizer bandwidth and total output phase noise is extracted. Based on this formula, the phase ...

QPSK Signal Detection Based on Two Duffing Oscillator

Due to great noise interference and strong signal attenuation in low voltage power line, two Duffing oscillator methods is proposed to detect QPSK carrier signal. At the same time, after analyzing the law of system solution of Duffing Oscillator, the algorithm of difference distribution of system solution is proposed to identify phase transition, which can greatly decrease calculation. The expe...
