A multi-rate adaptive waveform synchronization design and implementation in frequency-hopping systems is proposed in the paper, including the design and implementation of waveform frame structure and synchronization segment. In the structural design of the waveform frame, the synchronization segment is transmitted separately from the data segment, and the synchronization segment is concentrated in the frame header. In the design of synchronization segment, waveform recognition is carried out through multiple means such as the number of synchronization segment pulses and synchronization segment pattern, and the realization method of multi-rate waveform adaptive recognition is given at the receiving end, which effectively improves the recognition accuracy.
