Low False Alarm and Narrow-Wide Band Compatible Signal Detection Algorithm Combining the Multiscale Wavelet Transform Extremum Detection with the Spectrum Energy Detection

A low false alarm and narrow-wide band compatible signal detection algorithm is proposed by combining the multiscale wavelet transform extremum with spectrum energy detection. The signals different bandwidths are detected at respective scales. Signal a single scale adopts strategy of to decrease probability detecting spurious caused noises, noise floor estimation modification completed morphological filtering solve problem fluctuation. Finally, results multiple scales fused eliminated selectively. simulation show that able achieve excellent performance while realizing relatively signals.
