- Abstract
In this study, an enhanced short-time Fourier transform (STFT)-based jamming mitigation system which employs several windows to increase time--frequency (t-f) plane resolution is proposed. A technique for employing near-optimum windows is also proposed. It is observed that selection of these windows leads to increasing the resolution of the t-f representation. An infinite impulse-response notch filter is employed for jamming removal process. Performance of the proposed method is evaluated by a set of measured global positioning system data. It is compared with conventional STFT-based algorithms reported in literature.
