Abstract
|
|
|
A technique based on bispectrum averaging is described for generally recovering the signal waveform from a set of noisy signals with variable signal delay. The technique does not require explicit time alignment of signals and initial estimate of sigals and initial etimate of signal. The new method is suggested and is compared with other methods. This method are numerically investigated using computer generated-data and a phtsiological signal and noise. Some expermeental results for the evoked potential studies that demonstrate the technique are given. The results show the effectiveness of the technique : various potential applictions of the techique might be expected.
