PROJECT TITLE :

New GPS anti-jamming system based on multiple short-time Fourier transform

ABSTRACT:

During this study, an enhanced short-time Fourier rework (STFT)-primarily based jamming mitigation system that employs several windows to extend time-frequency (t-f) plane resolution is proposed. A method for employing close to-optimum windows is also proposed. It's observed that choice of those windows leads to increasing the resolution of the t-f illustration. An infinite impulse-response notch filter is used for jamming removal process. Performance of the proposed method is evaluated by a group of measured international positioning system data. It is compared with typical STFT-based mostly algorithms reported in literature.
