Краткое описание

A problem of unknown signal shape estimation in noise is considered. Combined bispectrum-filtering technique is proposed for signal waveform restoration by using higher-order spectrum properties in combination with linear or nonlinear digital filtering. Numerical simulation results demonstrating reconstruction of unknown signal waveform from an observed set of noisy realizations are represented. It is shown that combined signal processing strategy contained bispectrum-based signal shape reconstruction and nonlinear/linear filtering procedures provides better noise suppression in comparison to common types of bispectral, nonlinear and linear filters.
