摘要：
This paper presents a modified GCC for TDOA measurement with wavelet transform as the pre-filters. With high input SNR, the WT operation greatly reduces the computational load of GCC without accuracy degeneration. While in the case of low input SNR, the proposed method improves the performance of GCC by increasing SNR.
