摘要
传声器声源定位是利用传声器阵列拾取声音信号,并用数字信号处理技术对其进行分析和处理的声源定位技术。设计了一种基于MUSIC算法的声源定位系统,该系统以数字信号处理器(DSP)为控制核心,通过TMS320C6747高速数字信号处理器,提高了系统处理速度,简化了设计,能更好的满足声源定位的要求。经测试,该系统具有实时、高速、精度高及可靠性好的优点。
Microphone sound source localization is a kind of sound source localization technology, picking up sound signal by microphone array, analyzing and processing by digital signal processing. A sound source localization system based on MUSIC algorithm was designed, taking DSP as the controlling core. The processing speed of the system was improved through TMS320C6747 high speed digital signal processor. The design was simplified to bet- ter meet the requirements of sound source localization. Test result showed the system had the advantages of real- time, high speed, high precision and good reliability.
