However, this assumption is not always satisfied. The tasks of analyzing and synthesis are solved only for certain conditions. On the other hand, developed poly-Gaussian approach for describing of random variables with any possible distributions allows getting simple solutions in the cases when distributions are not Gaussian. In this paper, we present the uniform method of describing of any possible random variables in the form of continuous mixtures of Gaussian distributions using stochastic spectra. Distribution of the initial random variable is stochastic mixture of the known in the correlation theory distributions. Moreover, continuum stochastic spectra can error-free represent the random variables in the radio channels and equipment. New definition of limitless characteristic sets of unique stochastic spectra of any possible random variable is presented. Results of modeling exemplify this definition.","PeriodicalId":280881,"journal":{"name":"2018Systems of Signal Synchronization, Generating and Processing in Telecommunications (SYNCHROINFO)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116968127","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A subject of the analysis - the quasi-orthogonal signals ensembles based on the Gold sequences providing reliable division of channels at influence of imitation interference, signal-like noises and devices of their processing. The analysis purpose - optimization of the Gold sequences delay acquisition devices, capable to adapt to change of structure of the signals that make up the ensembles. The solution is based on the principles and mathematical models developed by authors: the principle of the fast conversions in Galois fields, algebraic model of representation and structure of fast delay acquisition devices for a subclass of the sequences based on the Gold sequences. The problem arises when using the very long sequences in the conditions of limited time of signal observation, high requirements to reliability and accuracy of synchronization, and also structural secrecy of the considered systems. In these conditions use of the various simplified procedures of fast delay acquisition is limited due to their low energy efficiency, while optimum parallel procedures are too difficult for implementation. The problem significantly becomes complicated when is needed achieve synchronization with a quasi-orthogonal signals ensemble, including signals ensemble with dynamically changeable structure applied in the conditions of influence of signal-like noises.This article is devoted to create of a processing method and model of a delay acquisition devices based on the fast conversions in Galois fields, close by efficiency to the optimum parallel scheme, and capable quickly adapt to use and (or) change of structure of Gold sequence on the basis of which ensembles of quasi-orthogonal signals make up. Key features of the described method of processing are implementation of correlation reception of set of synchronized short sequences samples having identical structure with accumulation of symbols from multiple copies of short sequences received from initial Gold sequence. The used principles of separate synchronization on delay components and fast conversions in Galois fields provide a big variety of options to create a delay acquisition devices providing a compromise between the speed and complexity of delay acquisition as it is reached in the known serial-to-parallel schemes.. It is shown that the proposed fast transformations models together with the offered delay acquisition devices provide a high level of adaptation to the signal structure change. The offered versions of the scheme of delay acquisition carry out reception and preprocessing of code sequences in real time that favorably distinguishes them from the known schemes, which are carrying out fast conversions by other methods. In particularly, there are no memory devices for storage of the accepted sample at a detection stage that usually is required at accomplishment of fast conversions by other methods.

The DRM standard provides the use of single-frequency synchronous broadcasting networks. Their application with competent frequency-territorial planning allows to increase the efficiency of the DRM broadcasting networks, as well as to save the frequency resource. The DRM single-frequency synchronous networks construction in general differs from the DVB-T/DVB-T2 synchronous digital television networks or VHF DAB/DAB + digital broadcasting networks construction due in the presence of ionospheric propagation of radio waves. These features are considered in this article. Method for calculating the synchronism zone is proposed. Consideration of possible scenarios for the placement of transmitters showed that the most advantageous can be considered their placement at an angle of 90 degrees. Tests of single frequency DRM radio network in the SW range with original methodology were conducted. Measurement results show that synchronous network gain reached the values up to 6 dB at a wire antenna and up to 11 dB at a whip antenna. When using traditional for broadcasting “day” and “night” frequencies it is possible to provide broadcast quality with high reliability (i.e., 98% audio decoding) within 24 hours.","PeriodicalId":280881,"journal":{"name":"2018Systems of Signal Synchronization, Generating and Processing in Telecommunications (SYNCHROINFO)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116099776","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is known that the geometry of antenna arrays imposes restrictions on the direction-finding performance. The most important one for the linear configuration is the possibility of only an azimuth estimate. To overcome this problem, flat and convex arrays were considered for tasks which required both azimuth and elevation direction-finding. The effect of the directivity of a single antenna element on the accuracy of determining the angular coordinates of radio emission sources of circular, cubic and spherical antenna arrays consisting of directed radiating elements has been studied. The limits of the directivity change of a singular element, which allow to achieve the maximum accuracy of the estimation of angular coordinates, have been determined. It has been shown that further increase of the directivity leads to the increase of mean square deviation when determining signal coordinates. The estimation of the resolving power of convex or volume antenna arrays depending on the directivity has been carried out. It has been established that the spherical antenna array has the best configuration.","PeriodicalId":280881,"journal":{"name":"2018Systems of Signal Synchronization, Generating and Processing in Telecommunications (SYNCHROINFO)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125473955","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accidents at marine facilities can occur for technical and organizational reasons, for example, as a result of exceeding permissible loads, wear of power cables, etc. The objects of monitoring, analysis, evaluation and forecast are aerological and process equipment.The key idea underlying the construction of the concept of an ideal fire alarm system is as early as possible the recording of the initial phase of fire development (IPFD) with a low probability of false positives. The technical result of the forecasting system for pre-emergency states consists in increasing the information content and quality of diagnostics of emergencies, expanding the scope of the device by using the mathematical model of the object for analyzing material and heat balances in forecasting emergencies. In accordance with the technical capabilities of the hardware and software complex to detect sources of pre-emergency situations in the scope of the protected premises, the requirements for an optoelectronic space control channel (OSCC) are determined. Given the technical capabilities of the hardware and software complex, the OSCC must automatically detect the change in the video frame with an area of at least 4–7% of the total area of the video frame, caused by the appearance of the following events in the field of view of the television (TK) or infrared camera (IR):–The appearance of an open flame area of at least 0.8 ÷ 1.0 dm2;–Penetration into the controlled space of moving objects with an area of at least 0.5 m2;–Occurrence of smoke, steam at an emission cross section of at least 0.8 ÷ 1.0 dm2;–Destruction of elements of equipment and technical means with the area of the fracture element not less than 1.5 dm2;–Offset of extended objects by an amount of at least 5 cm in a plane perpendicular to the axis of the camera;–Leakage of cisterns and pipelines in the event of a wet spot having an area of at least 1.5 dm2 referred to a surface perpendicular to the optical axis of the TK or IR lenses.Automatic detection of a pre-emergency situation will be performed when the TK or IR is in a stationary position and a constant image scale of no more than 25 ÷ 30 seconds.
