МЕТОД МІНІМІЗАЦІЇ ЧАСУ ДОСТАВКИ ПОВІДОМЛЕНЬ В МЕТЕОРНИХ КАНАЛАХ ЗВ’ЯЗКУ

Context. In special conditions, particularly during emergencies, when satellite and terrestrial communication channels become vulnerable or completely unavailable, communication via meteor burst channels can effectively serve as a backup or even a primary path for information transmission. The operational range of such a radio channel can reach up to 2000 km, and the absence of “dead zones” ensures broad territorial coverage that is comparable to other types of long-range radio communication. Objective Improvement of the method for one-way message transmission via meteor burst communication channels and its implementation algorithm, enabling minimization of message delivery time at a given reliability level.Method. Further development was achieved for the method based on minimizing the message structure through merging the address field with the synchronization flag. Additionally, a hybrid synchronization algorithm combining threshold and non -threshold signal processing is applied for the first time. To enhance reliability, the majority algorithm is utilized instead of classical ARQ methods through repeated message transmission.Results. An improved method for alert transmission over meteor-burst channels has been proposed, ensuring minimized delivery time and high reception reliability. Based on this method, a transmission protocol was developed, the message delivery time was evaluated, and synchronization techniques were identified, confirming the method’s effectiveness. The practical value lies in the development of an implementation algorithm suitable for deployment on DSP and FPGA platforms in alert systems without relying on satellite communication channels.Conclusions. The proposed method and implementation algorithm enable the minimization of short message delivery time at a specified reliability level and improve communication reliability under challenging conditions.
