Electrocardiography (ECG) signals are used for both medical purposes and identifying individuals. It is often necessary to encrypt this highly sensitive information before it is transmitted over any channel. A closed-loop acousto-optic hybrid device acting as a chaotic modulator is applied to ECG signals to achieve this encryption. Recently improved(More)
In the literature, the performance of multi-hop wireless networks is extensively analyzed over various fading channels subject to an additive white Gaussian noise (AWGN). However, and to the best of authors’ knowledge, the generalized Gaussian noise case has not been considered before. Motivated by this, we therefore analyze the system performance– in terms(More)
In this paper, we present a unified framework to analyze the performance of the average bit error probability (BEP) and the outage probability over generalized fading channels. Specifically, we assume that the probability density function (PDF) of the instantaneous signal-to-noise ratio ζ is given by the product of: power function, exponential function, and(More)
Acousto-optic Bragg diffraction with profiled input beams is numerically examined under open loop via a transfer function formalism. Thereafter, the scattered output is fed back to the acoustic driver, and the resulting nonlinear dynamics are examined to establish novel monostable, bistable, multistable and chaotic regimes
