摘要 在FPGA系统上实现了一个实时的数字传声器声源定位系统,包括信号预处理、语音活动检测、信号互相关运算三部分。FPGA实现声源定位,运算速度快,采用同样的算法可以完成多对传声器阵列的实时信号处理。该系统在15dB信噪比的环境中能够检测出声源入射的方向。 A FPGA implementation of a real-time sound localization using digital microphone array, including signal preprocessing, voice active detection and signal cross-correlation is presented in this paper. This system successfully localizes the source in noisy environments with as low SNR as 15 dB. With its rapid operation the same method can be used to deal with multi-microphone array in the future work.
