The ensemble averaged bispectrum을 이용한 유발전위 검출 알고리즘
Algorithm detecting an evoked potential using the ensemble averaged bispectrum
초록
A technique based on bispectrun 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 tune alignment of signals and any initial estimate of signal. The new method is suggested and is compared with other methods. This method are numerically investigated using computer generated-data and a physiological signal and noise Some experimental results for the evoked potential studios that demonstrate the technique are given. The results show the effectiveness of the technique: various potential applications of the technique might be expected.
