  • Speaker distance measurement using downsampled adaptive filter
    Publication number: 20060062398
    Abstract: A downsampled adaptive filter is used to find the impulse response of a home theater system. Downsampling yields higher maximum measurable distance for given filter length. By using a Least-Mean-Square (LMS) adaptive filter, almost anything can be used as the source noise. While downsampling may decrease the resolution of the distance measurement, Adaptive Filtering allows a much broader range of test signals, as opposed to MLS (Maximum Length Sequence) in which the test signal defines the technique (a pseudo-random Maximum Length Sequence.
