Guo Tai-liang · Audio Engineering · 2013
In terms of investigation on the principle of phase transform-generalized cross correlation(PHAT-GCC),this paper puts forward an improved phase transform-generalized cross correlation by several methods including monitoring signal-to-noise ratio,weighting signal-to-noise ratio,applying the coherence function and so on,which facilitate the more accurate estimation of time arrival difference.Experimental results prove the effectiveness of the presented algorithm.
