Digital Processing of Audio Signal and Its Application Design
【摘要】 提出了2.4G无线影音传输系统中的数字音频传输方案,介绍了AES/EBU数字音频接口标准,并详细阐述了系统的关键技术,包括差错掩盖技术和天线切换技术。采用差错掩盖技术,可以消除“噼啪”声;而运用天线切换技术,提高了音频信号接收质量,有效地抑制干扰,提升了系统的性能。
【Abstract】 The paper brings forward a digital audio transmission plan on the 2.4 G wireless video and audio transmission system, and AES/EBU digital audio interface standard is also introduced. Besides that, the key techniques in the system is explained in detail, including error concealment technique and antenna switching technique. The adopted error concealment technique gets rid of the noise of "pipa", and antenna switching technique can improve the quality of the received audio signal, restrain the noise effectively and promote the system performance.
