Abstract :
Three identification methods of wavelets in a noisy environment are presented. The amplitudes and lifetimes of these small pulses vary in an uncertain way. The chosen wavelets are memorised. They are, however, not known at the receiver. They are identified by the authors, for a signal energy to noise energy ratio >or=1 dB.
