Self-adaptive rate burst spread spectrum demodulation device for broadband anti-interference communication

The invention discloses a self-adaptive-rate burst spread spectrum demodulation device for broadband anti-interference communication, and relates to the field of broadband communication and the field of hidden satellite communication. Uniform chip clock processing is adopted, the clock processing frequency is reduced, parallel frequency sweeping, parallel capturing, parallel tracking and dispreading are applied, a data rate is analyzed through a recognition rate field and used for subsequent data dispreading demodulation, the data rate is variable burst by burst, the method can adapt to burst large-spread-spectrum-ratio data demodulation under Doppler frequency offset within a certain range, and the method is suitable for large-spread-spectrum-ratio data demodulation. The method is flexible and extensible, and is suitable for the vast majority of application scenes such as unmanned aerial vehicle communication in broadband satellite communication, covert communication behind missile-borne and other special we
