Abstract :
The paper introduces an improved version of the well-known frequency-domain LMS. We cope with the correlation problem by choosing the step-size according to the correlation factor and by using a novel delay-and-add algorithm which makes use of changes in the transmission room. The combination of these techniques allows the distortion of the loudspeaker signal to be minimized.
