This article presents a comparison of two methods for synthesizing digital filter prototypes. The first method based on the synthesis of the filter on a lattice structure, and the second iterative method based on minimizing the quadratic form. Both methods are applying with the fulfillment of the conditions of perfect reconstruction.

The article analyzes queuing systems’ stationary, ordinary recurrent streams of applications. The effect of correlation between the incoming flows of requests for queue sizes is determined. The article shows that the queue formation process in systems with a batched stream is cyclic. This process is divided into two sub-cycles: active and passive. Due to cycle analysis the generalization of the well-known Khinchin-Pollaczek formula is found. This formula was applicable only for Poisson queue flows before. The determined effect of correlations on the queue’s size is shown. The article proves that the maximum value of the covariation function’s integral of the applications’ number on intervals of the application’s service fully determines the middle size of queue into primary queuing systems with established load factor.

New properties of communication channel with intersymbol interference utilizing by APSK-N-signals are investigated. Based on estimates of the symbol error rate caused by intersymbol interference, the possibility of increasing the data transmission rate in the channel due to "transparency windows" is estimated. New properties have been identified that allow a significant increase in the efficiency of such communication channels.

Currently, there is a tendency to increase the speed of information transmission by increasing used frequency band. However, when switching to broadband signals and operating under conditions of a high level of noise, a wide dynamic range is required when digitizing the received signal. To increase the dynamic range, it is proposed to use a hybrid filter bank, which allows processing the broadband signal with low-speed precision analog-to-digital converters. In this paper, was calculated and simulated a hybrid analysis-synthesis filter bank for the 26.25 MHz-86.25 MHz frequency range. Using matched filters, we estimated the distortion of a linearly frequency-modulated signal during the passage of filter banks without intermediate processing, after upsampling and downsampling intermediate signals from the outputs of analog filters. To reduce phase shifts and time delays arising during signal processing by synthesis filters, compensation delays and phase shifts were introduced, adjusted to distortions carried by the processing system. It was shown that phase correction allows reducing signal distortions. It was also shown that in the case of receiving a mixture of signal and noise, the distortion introduced by the processing system does not significantly affect the signal-to-noise ratio of the output signal.

Spectral efficiency of the optical fiber within the cable construction signal transmission is being analyzed. Spectral efficiency modifying variety formed by bit/baud rate and frequency/wavelength spectrum bandwidth pairwise combining are being expanded to spatial multiplexing. Spatial – spectral efficiency category and parameter are proposed. Baud-wavelength efficiency parameter implementation is being discussed. Analytic equations are derived for signal transmission rate calculations using spectral efficiency parameter as input data. Signal transmission rate calculation examples are presented.

To describe the diffraction focusings of electromagnetic fields in the case when the family of primary (geometrical-optical) and secondary (edge) rays form a focusing of the cuspoid type, a method of local asymptotics has been developed. Expressions for the unfolding coefficients, the functional modulus, and the traveling wave phase are obtained.

This paper describes a blind two real signals separation method. Blind separation implies that there is no information about the signals except for received samples. This eliminates the presence of a systematic error in determining the stirring matrix and the restoration of the original signals. As a criterion for the separation of signals in this paper, the cumulants of the second and third orders of the output signals were reduced to zero. To test the performance of the method, mixing and separation model was created, and the efficiency of the method was tested at various power levels of the intrinsic noise in the receiving channels.
