摘要
对自适应噪声抵消技术进行了实验研究,成功地从强干扰信号中提取清晰语音信号,探讨 了自适应噪声抵消器的原理、当前应用情况及其前景,并进行了计算机仿真,给出了仿真结果.
Adaptive noise cancellation is experimentally studied in this paper. By receiving a speech signal with a special interference signal through the adaptive filter,the interference signal is effectively cancelled and a clear speech signal is gained. Some basic principles for adaptive cancellation and some typical application areas at present are discussed in the article. Finally, a result of computer simulation is also given.
