Abstract
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-system is increased and the overall-performance of an echo and noise cancellation has been improved.
