[Correlation noise detection in encephaloblood-fluidity signal].
The aim of this study was to remove random white noise which mixes with encephaloblood fluidity signal. Based on the principles of correlation detection and a priori knowledge of encephaloblood fluidity, the authors adopted the coherent averaging method and obtained pure encephaloblood fluidity signal. The result of practical use has demonstrated that the more times the averaging progresses, the more distinctly the wave shows up.
