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.

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.

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.

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.

The modern development of radio and radar facilities leads to the need to create special radio monitoring tools to monitor the electromagnetic spectrum. In the process of radio monitoring there is a need to detect and identify (recognition) of radio sources, in particular radars. The peculiarity of pulse radars is that the emitted radar signals can have both intra-pulse and inter-pulse modulation. There are quite a number of methods for recognizing types of pulse modulation (based on artificial neural networks, logical rules base, wavelet analysis, histogram analysis). Each of these methods uses its own set of features for recognition, which are certain parameters of the registered signal or the results of their special transformations. The effectiveness of recognition methods directly depends on the set of selected recognition features. The aim of the study is to select a dictionary of informative features for recognition of the following types of pulse repetition interval modulation (PRI) signals of radar: constant, stagger, sliding, dwell&switch, jittered, sin. To achieve this goal, two approaches were used: the choice of informative features using decision trees and the synthesis of informative features using an auto-associative neural network with a narrow throat. These approaches work well at the decision of tasks of recognition of radio signals. As a basic set of recognition features, statistical features of the distribution of the values of the pulse intervals of the radar signal proposed in [13], [14] were used: J1, J2, J3, f1, f2, f3, f4, f5.The analysis of different approaches to the selection of informative features showed that the mathematical apparatus of decision trees provides a better result compared to auto-associative neural networks. It is advisable to use features J1, J2, J3, f2 to recognize PRI modulation. At the same time, auto-associative neural networks allow to minimize the feature space without significant deterioration of its separating properties. Due to the reduction of the characteristic space at the stage of pre-processing of radio monitoring data, it is possible to reduce the computing power at the stages of identification of radio sources.
