Our Research

Development of radio components and communication systems based on high-speed software and hardware systems. Radio navigation, radar, meteor communications, signal processing, including 5-6G
Radio communication systems based on SDR technology
Data transmission systems of existing and next generations of communication (5-6G) are aimed at unification and flexibility of equipment that can be provided by SDR technology. One of the promising directions for increasing spectral efficiency is the application of SEFDM technology with smooth waveforms. The combination of these technologies can potentially achieve a significant positive effect with an increase in spectral efficiency
Digital signal processing, neural network technology, deep machine learning
The use of neural network technologies allows us to solve a wide range of problems in the field of signal processing. Real-time detection and classification tasks for radio signals, acoustic signals, objects in a video stream, etc. are effectively solved. The presence of high-performance computing platforms, for example, the Jetson NVidia or Raspberry series, allows implementing processing algorithms in the form of embedded systems. Video processing algorithms allow realizing high-precision optical measuring systems operating in real time. Using the optical flow method, a technology has been developed for measuring the fields of material deformation during laser welding
Development of equipment elements for advanced wireless communication systems
  • Phased array antenna transmitting module: it is a unit with an output power amplifier, a beam-forming device and a transmit / receive key. Using this device, the distribution of amplitudes and phases of the exciting electric currents of the antenna array is ensured, a certain type of antenna pattern and a method for scanning the main beam in space are implemented. This structure makes it possible to obtain 4 possible phase states at the output and, accordingly, to obtain 4 possible positions of the beam of the antenna array. Radio receiver: is a frequency converter module for input signals in the range from 800 MHz (optionally from 100 MHz) to 3000 MHz. The maximum tuning time from minimum to maximum operating frequency is 500 μs. The module is controlled via the CAN interface. The module design provides for the use of CompactPCI platform dimensions.
  • Transceiver module: a portable module for transmitting and receiving signals in the frequency range from 2.3 GHz to 2.7 GHz. The transmitting part of the module allows to achieve signal amplification up to 50 W and is based on a Doherty power amplifier, which is especially effective for signals with a high peak factor. The module also has a high-frequency predistortion system that provides high linearity. The receiving part is based on two cascades of low-noise amplifiers. Management is carried out using the UART interface. The module is enclosed in a compact package containing SMA type RF connectors, a Molex power and control connector and an integrated radiator in its design. Due to its size and characteristics, it can be widely used in various communication systems equipment.
  • Low-noise amplifier: is a symmetric high-linear LNA with ultra-low values ​​of the levels of intermodulation distortion of the second and third orders. The amplifier operates in the frequency range from 20 MHz to 1000 MHz, which allows it to be used in decimeter band communication systems, ISM, AM, FM, TV, and in cellular communication devices. Also, this LNA is used in broadband measurement technology, antenna measurements, laboratory research. An important distinguishing feature of the amplifier is the low-loss bypass mode when no power is supplied to the amplifier. The housing has a dust and water protection standard IP68″
