Удосконалення методу синтезу та розроблення імітаційної моделі завадостійкого кодування

Noise immunity is one of the most important characteristics of modern data reception/transmission systems. Improving noise immunity at fixed data reception/transmission speeds is an urgent problem, for example, for drone control. The studied code sequences allow increasing the power of the obtained sequences due to the use of mirror noise-resistant code sequences. Increasing the noise immunity of data transmission is achieved by increasing the length and power of the noise-tolerant code sequence used to transmit a single message. The advantages of these sequences, such as high noise immunity in relation to high-band narrowband noise, the possibility of dividing subscribers by code, transmission secrecy, high resistance to multipath, high resolution in navigation measurements will be widely used in communication and geolocation systems. The method for synthesizing noise-tolerant code sequences using ideal ring bundles is improved. The method for quick finding such noise-tolerant code sequences that are able to find and correct errors to the greatest extent depending on the length of the obtained code sequence is also improved. The algorithm for fast finding of such noise-tolerant code sequences, which are able to find and correct errors to the greatest extent depending on the length of the obtained code sequence, is implemented. A simulation model of noise-tolerant coding using ideal ring bundles is developed. The software implementation of the simulation model of noise-tolerant coding for finding and correcting errors in the obtained noise-tolerant code sequences is performed. The proposed noise-tolerant code sequences have practical value, as the resulting code sequence allows us to easily and quickly find up to 50 % and correct up to 25 % of distorted characters from the length of the noise-tolerant code sequence.
