On the basis of digital electronics technology digital audio system is used to reproduce audio signal and amplitude original signal level. So since the 1970s, digital signal and audio system technology have rapidly replaced existing analog audio signal and system in most areas especially mobile and wireless fields. Moreover because of trend of mobility, many electronic products have been downsized and further improved. In this paper, a design technology is introduced to implement compact and wireless digital audio system with noise cancellation algorithm based on the orthogonal transform. The proposed digital audio system is shown good operational characteristics such as signal distortion and efficiency and simple adaptive noise cancellation algorithm.
