Algorithms of implementation of vector-matrix multiplication are presented, which are intended for application in banks (sets) of digital filters. These algorithms provide significant savings in computational costs over traditional algorithms. At the same time, reduction of computational complexity of algorithms is achieved without any performance loss of banks (sets) of digital filters. As the basis for the construction of algorithms proposed in the article, the previously known Winograd method of multiplication of real matrices and vectors and two versions of the method of type 3M for multiplication of complex matrices and vectors are used. Methods of combining these known methods of multiplying matrices and vectors for building digital filter banks (sets) are considered. The analysis of computing complexity of such ways which showed a possibility of reduction of computing complexity in comparison with a traditional algorithm of realization of bank (set) of digital filters approximately in 2.66 times - at realization on the processor without hardware multiplier is carried out; and by 1.33 times - at realization on the processor with the hardware multiplier. These indicators are markedly higher than those of known algorithms. Analysis of sensitivity of algorithms proposed in this article to rounding errors arising by digital signal processing was carried out. Based on this analysis, an algorithm is selected that has a computational complexity smaller than that of a traditional algorithm, but its sensitivity to rounding errors is the same as that of a traditional algorithm. Recommendations are given on its practical application in the development of a bank (set) of digital filters.

The article studies the performance of a trained neural network SSD_MobileNet_V2_COCO. It is proposed to use the OpenVINO Toolkit to increase network performance. Performance evaluation is calculated by the reciprocal of the frame processing time, which characterizes the number of frames processed per second. Dataset COCO (by Microsoft) was used as the source dataset. In this case, 200 images were selected from this dataset, and during processing all images were reduced to the same sizes 300x300. Studies shown that the use of OpenVINO has increased the performance of the neural network SSD_MobileNet_V2_COCO by 130 times on average. At the same time, in contrast to starting a network using TensorFlow only, the variance of network performance using OpenVINO is significantly increased. However, the use of such an accelerator remains appropriate on Intel processors.

The purpose of the work is a comparative analysis of the influence of synchronization errors, namely, the errors of the carrier phase estimation and the errors of the clock synchronization system on the noise immunity of coherent receiving of signals with multi-position phase-shift keying and quadrature amplitude modulation. Using the method of statistical radio engineering, analytical expressions are obtained that allow calculating the probabilities of a bit error with static errors in estimating the phase and clock moments. It was shown that the inaccuracy in the estimation of these parameters strongly affected the noise immunity of the coherent receiving of multi-position phase-shift keying and quadrature amplitude modulation signals; with an increase in the positioning of the signals, this effect increases, and it is more pronounced for a multi-position phase-shift keying receiver. The permissible errors in estimating the phase of the carrier and clock moments for signals of different positioning are determined.

A structure of a refractometric fiber-optic biosensor with microwave photonics processing of information about refractive index of the medium surrounding the sensor is proposed. The sensor is made on a linearly chirped fiber Bragg grating and contains two phase $pi$-shifts spaced along the length of the grating in its structure: one fixed in magnitude and location, the second, changing its parameters, in the fiber section with an etched cladding. Upon contact of the measured medium with a portion of the fiber containing the second phase shift, there is a change in its magnitude and frequency position, depending on the refractive index. The possibility of detecting changes in the refractive index with a resolving power of $1.5times 10^{-6}$ RIU is shown.

The article is devoted to the algorithm for joint estimation of the non-stationary channel and signal distortions in the direct conversion receiver, based on the use of polynomial approximation in the time domain of the channel matrix elements and the linear least squares method (MLS). This approach has simplicity and relatively low computational complexity. The algorithm works under conditions of a priori uncertainty regarding channel statistics in the presence of phase noise, Rayleigh fading, and Doppler spreading.
