Abstract
This thesis studies the use of orthogonal components applied to update the least mean squares algorithm, and it's application in acoustic echo cancelation. The new adaptive algorithm is called the Decorrelation Algorithm (DCR) in the thesis. The mathematical properties of this algorithm is discussed and its performance compared to the NLMS algorithm for acoustic echo cancelation. The results obtained in this study provide a means of supporting hands-free telephone conversation where the participants are able to move freely within an office, or living room and full duplex conversation can be carried out between the speakers.
