Adaptive filtering with DC bias compensation

A filter, comprising:

• a delay element configured to serially receive a plurality of samples;
• a coefficient generator configured to adapt a plurality of coefficients;
• a first multiplier configured to multiply said one of the filter coefficients with the parameter;
• a second multiplier configured to multiply each remaining filter coefficient with one of the samples from the delay element;
• and
• an adder configured to sum the parameter and the samples;
• wherein the adaptation of the filter coefficients is a function of the summed parameter and samples.

Computer-readable media embodying a program of instructions executable by a computer program to perform a method of adapting filter coefficients, the method comprising:

• adapting a plurality of filter coefficients;
• and
• filtering a plurality of samples by applying one of the filter coefficients to a parameter, applying each remaining filter coefficient to one of the samples, and combining the parameter and the samples;
• wherein the adaptation of the filter coefficients is a function of the combined parameter and samples.

A filter, comprising:

• means for adapting a plurality of filter coefficients;
• and
• means for filtering a plurality of samples by applying one of the filter coefficients to a parameter, applying each of the remaining filter coefficients to one of the samples and combining the parameter and the samples;
• wherein the adaptation of the filter coefficients is a function of the combined parameter and samples.
