摘要

本文提出了一种利用心理声掩蔽效应进行声学系统识别的正交完全相关序列算法及其实现。因此，对常用的nlms算法进行了改进，加入了隐藏的正交Ipatov-和Huffman序列，以实现系统的快速识别。该方法提高了扬声器-房间-麦克风(LRM)系统识别的速度和精度，提高了回波和噪声消除的综合性能。

Psychoacoustical excitation of the (N)LMS algorithm for acoustical system identification

This paper presents an algorithm and an implementation of orthogonal perfect correlation sequences for acoustical system identification using psychoacoustical masking effects. Therefore, the common NLMS-algorithm has been modified to incorporate hidden orthogonal Ipatov- and Huffman sequences for fast system identification. Using this method, the speed and accuracy of the identification of the loudspeaker-room-microphone (LRM)-system is increased and the overall-performance of echo and noise cancellation has been improved.
