Abstract
In recent years, source localization system bad on microphone array is being widely ud in the videoconference, teleconference, speech enhancement, hearing aids. So it has been received a growing interest and become a very hot area. In various source location method, time difference of arrival (TDOA)bad on the double step method is the most widely ud, which has simple principle, low calculated amount, high precision, and can realize real-time in practice. The paper also focus on this method.
diss是什么意思中文Firstly, the hardware design of the source localization system bad on microphone array is been prented. Multi-channel microphone signal can be sampled at a certain sampling frequency in the same time in this design. Secondly, bad on the single chip Single-Chip microcomputer of STM32F103RBT6, standard and advanced communication interfaces. The features make the STM32F103 line microcontroller family suitable for a wide range of applications. The critical ction
