[VOIP program] EchoCancellationinIPTelephoneSystem DL : 0: 分析了IP 电话系统中回声的特点, 并针对其回声具有路径延迟、延迟抖动大等特点, 提出了一种基于延迟分析的自适应回声消除器设计的新思想和相关算法。介绍了自适应回声消除器的基本结构及各个功能模块, 例如: 变阶数自适应滤波器, 语音状态检测器, 延迟分析器和NLM S 算法控制器. 本文还详细论述了以TM S320C6201DSP 为硬件平台来实现能运用在IP 电话网关中的自适应回声消除器及其在IP 电话系统中的连接关系。在文章的最后, 列举了对自适应回声消除器的性能测试结果, 并分析了自适应回声消除器的优点, 证明了自适应回声消除器能很好地解决IP 电话系统中的回声消除问题。-Analysis of the IP telephone system in the characteristics of echo, and echo with a path for its delay, delay jitter features and so on, the A delay based on the analysis of adaptive echo cancellation design of the new ideas and related algorithms. Introduced the adaptive echo cancellation device The basic structure and the various functional modules, such as: change the order of adaptive filter, voice status detector, the delay count analyzers and NLM S Law controller. This article also discussed in detail in TM S320C6201DSP to achieve for the hardware platform to use in the IP Phone Gateway Adaptive echo cancellation and its IP phone system in the connections. Finally, listed on the adaptive echo canceller The performance test results and analysis of the adaptive advantages of echo cancellation devices to prove that the adaptive echo canceller can be a good solution to IP Telephone system in the echo cancellation problem.
