Spread spectrum algorithm resistance to wideband non-stationary interference
Abstract
This study proposes a multi-ary modulation chirp spread spectrum algorithm specific for the unmanned aerial vehicles field. It further introduces the corresponding fractional Fourier transform de-spreading algorithm and the hardware implementation of the software radio-based communication system to validate the algorithm's better anti-interference performance in the wide-band non-stationary interference environment.
