Description
Summary:碩士 === 淡江大學 === 資訊工程學系 === 87 === Due to the great advance in the technique of microprocessor and the sharp drop of cost, digital signal processing applications are widely spread. In addition, the array signal processing technique has been vibrantly developed, no matter in noise deduction or in signal enhancement we have achieved certain degree of satisfactory result. Another interesting application of array signal processing is to use multi-sensors to estimate the signal source. In this thesis we investigate methods in array signal processing and implement a system for estimating the source location of a sound. Our system is a real-time embedded system implemented with Texas Instrument TMS320C542 StarterKit. Like all animals with two ears, we use two sensors (microphones) to receive input sound and estimate the location of the sound source. We shall apply all benefits from array signal processing in noise deduction, signal enhancement and sound source estimation in our system. We hope our system can be further developed a hearing aid system for human being.
