In particular, radio pulse passage with the intra-pulse angular modulation is investigated; the systems with phase and frequency shift keying are studied.

The use of ultrasonic and radio engineering technologies for underwater data transmission does not primarily provide the required transmission speed. The transmission speed can be significantly increased if electromagnetic waves of the optical range are used as carriers. Analytical methods are often used to evaluate the characteristics of hydrospheric optical communication channels, in particular attenuation, but such methods do not take into account many features of the propagation of optical radiation in the hydrosphere. For example, the Lambert-Beer law used to calculate the channel attenuation cannot be used in a medium with high turbulence. The article presents a statistical model of the optical wave propagation based on the Monte Carlo numerical simulation method. This channel model can be used to estimate the spatial and temporal distribution of photons, communication range, taking into account both unscattered photons and single scattered and multiple scattered ones. The simulation results can be used to predict various design parameters of underwater optical communication systems.","PeriodicalId":255578,"journal":{"name":"2020 Systems of Signal Synchronization, Generating and Processing in Telecommunications (SYNCHROINFO)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132811041","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}

At the same time, maximum, minimum and average values of indicators are widely used. In such operations, it is not taken into account that if the values of the indicators are in the range of permissible values, then the quality of the network connection is considered acceptable. It is most advisable to take into account the magnitude of the deviation of the indicator values from the areas of permissible values and the duration of such deviations. In this case, the deviation value will characterize the amount of network performance degradation, and the duration of the deviation will characterize the duration of the performance degradation. The network performance assessment thus formed will closely characterize the perception of the quality of the communication service by the user of the communication service. This article focuses on the development of such network performance metrics.","PeriodicalId":255578,"journal":{"name":"2020 Systems of Signal Synchronization, Generating and Processing in Telecommunications (SYNCHROINFO)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128205564","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}

The transmission side of the system was investigated earlier, and the structure of its emission field was analyzed in details. Collective information transmission with $N$ independent, yet synchronous ultra-wideband chaotic transmitters increased signal-to-noise ratio at the receiver input by a factor of $N$. Here, a multi-element energy receiver (ensemble of envelope detectors) is investigated analytically. As is shown, the use of $N$-element receiving system increases the output signal-to-noise ratio by another factor of $N$. Thus, the overall effect of $N$ transmitters plus $N$ receivers is an increase of the output signal-to-noise ratio by a factor of $N^{2}$, which means $N$-times larger communication distance.","PeriodicalId":255578,"journal":{"name":"2020 Systems of Signal Synchronization, Generating and Processing in Telecommunications (SYNCHROINFO)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133678070","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}

At $tau_{2} =0$, there remains the only boundary of $gamma$-type, which separates the loci of hysteresis and non-hysteresis types. In this case, as the whole diagram shows, the OS resonance points are locally stable if they are located to the left of the $gamma$-boundary and globally stable to the right of the boundary.

To estimate that errors in the experiments we developed a hardware software complex. The measurements were simultaneously gathered from multiple receivers located in the area with a radius smaller than the correlation radius of TEC variations. Based on the developed analytical model we showed that, at a constant SNR, the transionospheric channel capacity increases with an increase in the channel bandwidth, significantly exceeding the channel coherence bandwidth. It was found that the errors in measuring TEC limits the possibilities of spreading channel bandwidth and increasing capacity. Experimental studies showed that under the presence of errors, the gain after correction depends on the season of the year and was observed 2.5 … 7 times.","PeriodicalId":255578,"journal":{"name":"2020 Systems of Signal Synchronization, Generating and Processing in Telecommunications (SYNCHROINFO)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129550438","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}
