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.
