DETECTION SIGNAL DELAY METHOD, DETECTION DEVICE AND ENCODER
摘要
<p>A method of improving the accuracy of detecting signal delay, detection device and encoder are provided. The method includes: based on the cross-correlation function among the sound channel signals, acquiring a first accumulation cross-correlation function; determining the corresponding first delay of said first accumulation cross-correlation function among sound channel signals; adjusting second accumulative cross-correlation function based on the relationship between the first delay and the second delay among the sound channel signals, when the second accumulative cross-correlation function is adjusted, the said second delay is acquired and the first value of said second delay is determined based on a initial value of second weighting coefficients of the second accumulation cross-correlation function; determining adjusted corresponding second delay of the second accumulative cross-correlation function as the delay among detected sound channel signals.</p>
