A series of short time stochastic resonance (SR) phenomena, realized in a bistable receiver, can be utilized to convey train of information represented by frequency-shift keying (FSK) signals. It is demonstrated that the SR regions of the input noise intensity are adjacent for input periodic signals that differ in frequency appropriately. This establishes the possibility of decomposing M-ary FS...

This study proposes a heterogeneous in-band full-duplex system for the simultaneous transmission of existing wireless smart ubiquitous network (Wi-SUN) using IEEE 802.15.4g-compliant frequency-shift keying utility (SUN-FSK) and reception next-generation Wi-SUN 802.15.4-2020-compliant orthogonal frequency-division multiplexing SUN (SUN-OFDM). In particular, we propose digital self-interference (...

We discuss the application of coding and modulation for power-line communications. The results are based on models derived from realistic channel measurements in existing networks and are in agreement with existing standards. Introduction This papers discusses several aspects of communications over the low voltage distribution lines. We first discuss a modulation scheme know as M-tone signaling...

k-distribution-based approaches are promising models for radiation calculations in strongly nongray participating media. Advanced k-distribution methods were found to achieve close-to benchmark line-by-line (LBL) accuracy for strongly inhomogeneous multi-phase media accompanied by several orders of magnitude smaller computational cost. In this paper, a k-distributionbased portable spectral modu...

Channel gating of the cystic fibrosis transmembrane conductance regulator (CFTR) is activated in response to cAMP stimulation. In addition, CFTR activation may also involve rapid insertion of a subapical pool of CFTR into the plasma membrane (PM). However, this issue has been controversial, in part because of the difficulty in distinguishing cell surface vs. intracellular CFTR. Recently, a full...

Conventional CubeSat radio systems typically use one of several basic modulations, such as AFSK, GMSK, BPSK, QPSK and OOK or switch between them on demand if possible. These modulations represent a balanced trade-off between good energy efficiency of high order M-FSK modulation and good spectral efficiency of high order M-QAM modulation. Utilization of modulations with the best energy efficienc...

In this paper, a multiple-access spread-spectrum communication system using binary frequency shift keying (BFSK) or M -ary frequency shift keying (MFSK) and noncoherent demodulation is considered. In contrast to previous work typically assuming that the frequency shift keying (FSK) tones are nonoverlapping after direct-sequence (DS) spreading, here we consider a spread-spectrum multiple-access ...

This paper presents a smartguide prototype based on the detection of high frequency acoustic signals by means of the user’s portable device. An FSK communication protocol is used to tag the different exhibitions ensuring at the same time high tolerance to the Doppler shift caused by the user’s movement. This system has been implemented on an Androidbased platform to obtain a set of preliminary ...

A series of short-time stochastic resonance (SR) phenomena, realized in a bistable receiver, can be utilized to detect a train of information represented by signals that adopt frequency-shift keying (FSK). It is demonstrated that the values of noise intensity at resonance regions are close for adjacent periodic signals with an appropriate frequency separation. This establishes the possibility o...
