Patent ID: 6999509

Claim:
A filter adaptation unit suitable for producing a set of filter coefficients, said filter adaptation unit comprising: a) a first input for receiving a sequence of samples of a first signal; b) a second input for receiving a sequence of samples of a second signal, the second signal including a component which is correlated to the first signal; c) a scheduling controller operative for generating a scheduling sign including a succession of scheduling commands, the scheduling command indicating that a new set of filter coefficients is to be computed, the scheduling signal being such that a new scheduling command is issued when at least two samples of the first signal are received subsequent to a previously issued scheduling command; d) a processing unit operatively coupled to said first and second inputs, said processing unit being responsive to a scheduling command from said scheduling controller to generate a set of filter coefficients at least in part on the basis of said first and second signals, the set of filter coefficients being such that when the set of filter coefficients are applied by a filter on the first signal, an estimate of the component in the second signal is generated, the component being correlated to the first signal; e) an output for releasing an output signal indicative of the set of filter coefficients generated by the processing unit.
