摘要：

In this paper, we present an FPGA-based real-time voice signal preprocessing system that can compute the cross-correlation of the voice signals from number of microphones. Each cross-correlation is calculated using voice signals captured within 200 ms which has 10 ms shifting window. The sampling frequency of the proposed system is 48 KHz; and the resolution of each sample is 16 bits. The entire algorithm is implemented in hardware based on FPGA and runs in real-time.
