What is RLS adaptive filter?

The RLS adaptive filter is an algorithm that recursively finds the filter coefficients that minimize a weighted linear least squares cost function relating to the input signals. These filters adapt based on the total error computed from the beginning.

What is LMS adaptive filter?

Least mean squares (LMS) algorithms are a class of adaptive filter used to mimic a desired filter by finding the filter coefficients that relate to producing the least mean square of the error signal (difference between the desired and the actual signal).

What is adaptive filter in DSP?

Adaptive filters are digital filters whose coefficients change with an objective to make the filter converge to an optimal state. The optimization criterion is a cost function, which is most commonly the mean square of the error signal between the output of the adaptive filter and the desired signal.

What is the main advantage of adaptive filter?

Adaptive filters are commonly used in image processing to enhance or restore data by removing noise without significantly blurring the structures in the image.
