Adaptive optimal kernel smooth-windowed wigner-ville bispectrum for digital communication signals
Higher-order timefrequency distribution (HO-TFD) outperforms the bilinear TFD in noisy conditions but suffers more severely from cross-terms when used to analyze multi-component signals. Various kernel functions have been introduced to suppress cross-terms in bilinear TFD but in general TFD with a f...
