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

The DSP Blockset provides a collection of adaptive filtering demos to illustrate typical applications of these blocks:

• LMS Adaptive Equalization (lmsadeq)
• LMS Adaptive Linear Prediction (lmsadlp)
• LMS Adaptive Noise Cancellation (lmsdemo)
• LMS Adaptive Time-Delay Estimation (lmsadtde)
• Nonstationary Channel Estimation (kalmnsce)
• RLS Adaptive Noise Cancellation (rlsdemo)

Open the demos by clicking on the demo names above in the MATLAB Help browser. Alternatively, open the demos by typing the demo name (provided in parentheses above) at the MATLAB command line.
