摘要
Abstract
As the sixth-generation(6G)mobile communication technology advances toward the physical layer architecture revolution,breaking the barriers of traditional waveform design in terms of latency and overhead becomes a key breakthrough for achieving microsecond-level ultra-low latency transmission.This paper proposes a synchronization and data integration-based waveform design to address the excessive frame structure waiting delay and processing delay in short packet low-latency services.The design adopts a sequence communication concept,mapping data information into a combination of multiple sequences with linear random phases.At the receiver,synchronization and identification of the transmitted sub-sequences are performed using correlation,tightly coupling synchronization and data transmission while reducing the overhead of channel estimation.A generalized chirp sequence sequence pool construction method is introduced,and the compatibility with the sequence communication framework is analyzed theoretically.Additionally,a bit mapping scheme based on Bose-Chaudhuri-Hocquenghem coding is implemented at both the transmitter and receiver,and fractional-order Fourier transform is employed for fast demodulation.Simulation results show that the proposed waveform design exhibits superior synchronization performance and lower bit error rates under various channel conditions,laying the foundation for ultra-low latency transmission in 6G systems.关键词
