When transmitting music signals via infocommunication channels, there is a risk of distortion of these signals due to clipping. The consequence of these distortions is a decrease in subjective assessments of the quality of musical signals, so clipping detection is an important issue. In this paper, the kurtosis and the inverse value of kurtosis are proposed as measures of an objective assessment of the musical signals clipping degree. Matching maps of objective and subjective clipping degree estimates are monotonic functions that do not contain sharp kinks, which allow not only evaluating clipping degree, but also estimating music signals quality. An important advantage of the proposed measures of the clipping degree is the ability to simplify and speed up significantly the calculations due to the absence of the need of preliminarily estimation the probability density function of the analyzed musical signal.

A method of compensation for trajectory instabilities of aviation radars with aperture synthesis is proposed. This method allows the further processing of the received signals to consider that the aircraft or the radar carrier is moving along a predetermined trajectory. The estimation of the relative instability of the generator frequency for the microwave range was obtained. It is determined that the exact compensation of trajectory instabilities by measuring this deviation and compensating for it by changing the time interval between the sensing pulses and the received signal is required for each inclined channel. An algorithm for calculating the radar inspection sub-band width is proposed. The use of the proposed method will provide the ability to achieve a resolution better than 4 … 8 meters in the radar synthesizing aperture in the fluctuations of the trajectory of motion of the radar carrier relative to the line of the specified path more than half the resolution almost regardless of the altitude, the degree of turbulence the operating speed and mass of the radar carrier.

The wide application of FPGA chips becomes a trend in telecommunications and wireless communications era. Proposed approaches for safety-critical embedded systems and telecommunication systems design for avionics based on FPGA. In this paper, we will analyze the different approaches to security and safety in embedded systems for avionics. In addition, we analyze the different approaches to safety-critical embedded systems and for avionics based on FPGA. Avionics is an advanced and integrated system that has strong requirement of flexibility, high bandwidth, and stringent end-to-end latency. In article analyzed the avionic wireless network and fly-by-wireless concepts also.

Novel method of radio relay link bandwidth capacity improvement based on spatial signal processing by the wave front of the electromagnetic wave are presented. Test results of a variant of one-hop simplex radio relay link lab prototype with spatial signal processing both in the transmitting and receiving sites are shown. This prototype provides simultaneous parallel wireless transmission of two DVB-C radio signals with 64-QAM modulations at bit rates of 41.25 Mbps over 8 MHz bandwidth with the same carrier frequency of 10.56 GHz and with the same electromagnetic waves polarization at distance of 8 meters. This prototype can be used for research the possibility of radio frequency resource reuse and bandwidth capability improvement for radio relay links by applying spatial signal processing techniques.

In this paper we presented the results of cloud computing and analysis of orbital parameters of the satellite fragments that formed by first India anti-satellite (ASAT) missile against a "live" Microsat-R satellite launched by them on January 24, 2019. Based on the cloud computing we calculated the orbital parameters and distribution of impulse values obtained by Microsat-R fragments that were formed after the impact of ASAT missile and tracked by NASA. All results in this paper and detailed analysis of this event are based on the orbital data taken in form of NORAD two-line element (TLE) dataset from space-track.org and by own calculation of the CoLiTec group in EOS Data Analytics using own cloud server. The test parameters were chosen with extreme caution to minimize the hazard of debris after the impact. However, the results of our research showed the significant differences from expected "head-on collision" of rocket with Microsat-R satellite.
