摘要
本文在综述平坦时延估计算法的基础上,对相关算法进行了计算机模拟,得到了最小抽头数选取的依据(M=1.1N),还探讨了语音白化软件的实现和基于相关平坦时延估计算法的回波抵消器实现方案。
On the basis of algorithm of the flat time-delay estimation, the computer simulations of correlation algorithm are made. The selection criterion (M=1.1N) of minimum tap number is obtained. The realization of whitelization software and the realization scheme of the echo canceller based on correlation algorithm of flat time-delay estimation are discussed.
