  • METHODS FOR DESIGNING HIGH FREEDOM PARAMETERIZED FREQUENCY-MODULATED CODED WAVEFORM
    Publication number: 20250231579
    Abstract: The embodiments of the present disclosure provide a method for designing a high freedom parameterized frequency-modulated coded waveform, comprising: S1: obtaining a frequency-modulated coded vector; S2: selecting a coding model order to be utilized; S3: obtaining an parameterized instantaneous frequency function of a signal based on the frequency-modulated coded vector and the coding model order, integrating the parameterized instantaneous frequency function to obtain a phase of the signal, and generating the high freedom parameterized frequency-modulated coded waveform. Embodiments of the present disclosure provide a high freedom parameterized frequency-modulated coded waveform. The waveform has a continuous phase function, precise spectral control, and is configured to have a parameterized frequency-modulated waveform with high freedom.
