Combat jamming with adaptive notch filtering or wavelet mitigation: a comparison

January 14, 2016By
Power Spectral Density comparison (fs=112 MHz; fif=28.42 MHz; Bif=30 MHz).

Wavelet Packet Decomposition (WPD) shows promise as an anti-jamming tool. The WPD is derived from the wavelet transform, which provides a representation of the signal components in a domain spanned by a set of functions that can be seen as band-pass filters with a bandwidth decreasing as their central frequency increases, thus granting a uniform resolution in the decomposition of... read more
