Design and hardware verification of compensation algorithms of pattern distortion for multiple beams antennas.
January 2017 – December 2017
The goal of the project was the development of algorithms and a testbed to compensate for the impairments of a satellite antenna system with multiple beams. Perturbation of the antenna reflector is considered the main source of the impairments. As a result of the project, a digital pattern distortion compensation algorithm was proposed based on the pilot signals. Performance verified via measurement as the NI testbed.
Research and development of recognition algorithms for the video processing module of adaptive front-light control system.
January 2016 – February 2017
The goal of the project was to design a processing chain for object detection and control of an adaptive-front light system (AFS, part of ADAS). During the project, an AFS prototype was developed and tested on the dataset for various road conditions. Additional evaluation of system performance and the importance of detection features was carried out.
Development of waveguide mode converter for radio direction finder and test equipment to it.
May 2015 – November 2015
The goal of the project was to simulate the work of a radio direction finder for the K-band and then develop test equipment. The measurement platform was built on the equipment from NI. The software was designed in LabView. The complex could measure radio direction finder response characteristics, store signals in real time to RAID, and extract quality parameters from the measured data.
Development of digital processing module for a prototype of a beacon transponder.
September 2013 – January 2014
In this work, a prototype of a technological beacon transponder for an air traffic control radar beacon system (ATC RBS) was developed. The prototype consisted of National Instruments equipment and the Altera FPGA development board. The technological beacon transponder is test equipment for secondary surveillance radars (air traffic control radar beacon system) that is used for equipment verification at civil airports. Within the project, the receive algorithm was developed and tested by NI equipment; later, it was transferred to the Altera FPGA development board.
Research and development of a prototype for OFDM based communication system.
January 2012 – December 2012
The goal of the project was the investigation of the OFDM technology. Particular focus was placed on analyzing the time- and frequency-synchronization algorithms. During the project, I created the architecture for the transceiver design and developed the corresponding algorithms for signal processing. Further, the performance was analyzed at the NI-SDR testbed with physical signals.
Development of software for automated system for antenna measurements.
April 2011 – October 2011
The project aimed to build the control software for an automatic antenna measurement system. The corresponding measurement system was built on the vector network analyzer from National Instrument equipment. The control systems facilitated the measurements of antenna parameters, such as diagram pattern, matching coefficient, polarization, etc. All software was developed in the graphical programming environment Labview within the project.
