A short reference differential chaotic shift keying communication system based on signal scrambling transformation (RSST-SR-DCSK) is proposed in this paper. The introduces information-bit-driven scramblers at the transmission end to effectively eliminate correlation between and information signal. At receiving end, a descrambler used restore correlation, thereby enhancing security. Additionally, employs mechanism further increase rate. transmitter receiver structures of are designed through structure analysis. Theoretical analyses simulations conducted an additive white Gaussian noise (AWGN) channel demonstrate promising performance, including low bit error rate (BER) favorable data-energy-to-bit-energy ratio (DBR). Simulation verification performed examine impact parameters performance. comparative analysis with traditional DCSK SR-DCSK systems highlights superior performance RSST-SR-DCSK system.
