Adaptive Filters

Adaptive filters are filters whose transfer function coefficients or taps change over time in response to an external error signal. The Adaptive Filters library contains the following blocks:

• Kalman Adaptive Filter
• LMS Adaptive Filter
• RLS Adaptive Filter

Adaptive Filtering Demos

The DSP Blockset provides a collection of adaptive filtering demos that illustrate typical applications of the adaptive filtering blocks, listed in the following table.

Opening Demos.   To open the adaptive filter demos, click on the links in the following table in the MATLAB Help browser (not in a Web browser), or type the demo names provided in the table at the MATLAB command line. To access all DSP Blockset demos, type demo blockset dsp at the MATLAB command line.
