Achievable error exponents for the one-way with noisy feedback and two-way AWGN channels are derived transmission of a finite number messages M under almost sure (AS) expected block (EXP) transmit power constraints. In setting feedback, an AS constraint, known linear non-linear passive schemes modified to incorporate constraints in link as well. addition, new active scheme is presented which re...

this paper addresses synchronizing two coupled chaotic fitzhugh–nagumo (fhn) neurons with weakly gap junction under external electrical stimulation (ees). to transmit information among coupled neurons, by generalization of the integer-order fhn equations of the coupled system into the fractional-order in frequency domain using crone approach, the behavior of each coupled neuron relies on its pa...
