В данной работе представлен метод снижения пик-фактора (PAPR) в гибридных спутниковых сетях связи с использованием методов ортогонального доступа и формирующих фильтров. Предложенный подход объединяет гибкие защитные интервалы и методы формирующей фильтрации для оптимизации передачи сигналов в низкоорбитальных спутниковых сетях. Исследованы несколько типов фильтров, включая приподнятый косинус (RC), корень из приподнятого косинуса (RRC), полосно-настроенный приподнятый косинус (BTRC) и его оптимизированную версию (OBTRC). Предложен новый вариант формирующего фильтра на базе OBTRC. Метод оценивается с использованием технологий OFDM и DFT-s-OFDM с модификациями нулевого хвоста и уникального слова. Результаты моделирования показывают снижение PAPR на 0.5-2 дБ по сравнению с традиционными подходами.

This paper presents a method for peak factor (PAPR) reduction in hybrid satellite communication networks using orthogonal access methods and shaping filters. The proposed approach combines flexible protective intervals and formative filtering methods to optimize signal transmission in low-orbit satellite networks. Several types of filters have been investigated, including the raised cosine (RC), the root raised cosine (RRC), the «better than» raised cosine (BTRC) and its optimized version (OBTRC). A new variant of the shaping filter based on OBTRC one is proposed. The method is evaluated by emulation low-orbit satellite communication networks. OFDM and DFT-s-OFDM technologies with zero-tail and unique word modifications. The simulation results show a decrease in PAPR by 0.5-2 dB compared to traditional approaches.
