The proposed method reduces Peak-to-Average Power Ratio in satellite networks, suggesting improved signal transmission.
This paper presents a method for Peak-to-Average Power Ratio (PAPR) reduction in hybrid satellite communication networks utilizing orthogonal access methods and shaping filters. The proposed approach combines flexible guard intervals and shaping filtering techniques to optimize signal transmission in low-orbit satellite networks. Several filter types are investigated, including Raised Cosine (RC), Root Raised Cosine (RRC), Band-Tuned Raised Cosine (BTRC), and its optimized version (OBTRC). The method is evaluated using OFDM, OFDMA, and DFT-s-OFDM variants with zero-tail and unique word modifications. Simulation results demonstrate a PAPR reduction of 2-4 dB compared to conventional approaches, with DFT-s-OFDM-based technologies exhibiting superior performance even under challenging channel conditions with Doppler shift.
