The first stage in the construction of an effective subsystem for monitoring technical state communication devices and navigation equipment is to analyze development modern information telecommunication systems public networks. analysis will make it possible find solutions problem improving safety. study aims develop a method device distributed based on self-contained vessel or unmanned aerial ...

The potential applications of optical resonant filters for optical communication systems can be significant. Three approaches to achieve a close-to-rectangle filtering profile for optical resonant filter were investigated and proven experimentally. The combination of the filtering sharpness, which comes from the resonance nature, and a flattened filtering window realized the close-to-rectangle ...

Atmospheric turbulence can cause a significant performance degradation in free space optical communication systems. An efficient solution could be to exploit the temporal diversity to improve the performance of the transmission link. Depending on the tolerable delay latency, we can benefit from some degree of time diversity that we can exploit by employing channel coding and interleaving. In th...

Voltage control is one of the imperative issues in the smart distribution control system. While traditional distribution network is equipped with communication and monitoring equipment, the online voltage control can be perfectly achieved. With using these smart grid technologies, the distribution voltage control schemes should carry out intelligently and cover the undesirable effect of high pe...

− We demonstrate an ultra-stable visible laser source that can be generated from injection locked infrared DFB based on optical comb. The optical comb was used as injection source and locked to an acetylene stabilization laser as a reference source of optical communication region. The DFB laser was selectively injection locked from only one among the comb mode with 25 GHz spacing. The ultra-sta...

The interplay between the stochastic intensity fluctuation of Raman pump laser and cross-phase modulation (XPM) effect in transmission optical fiber leads to additional phase noise, namely, relative phase noise (RPN) of signal in multi-level modulated coherent optical communication system. Both theoretical analysis and quantitative simulation have been performed to investigate the characteristi...

Today, the equipment of electronic communication networks (EECN) consists two interconnected components. The first is hardware, second software, normal functioning each which depends on network in general. One main concepts characterizing network's ability to perform tasks as intended functional safety (FS). This concept similar reliability, but differs mainly that context all possible failure ...

We introduce low complexity machine learning method method (based on lasso regression, which promotes sparsity, to identify the interaction between symbols in different time slots and to select the minimum number relevant perturbation terms that are employed) for nonlinearity mitigation. The immense intricacy of the problem calls for the development of "smart" methodology, simplifying the analy...
