Patent ID: 7339990

Claim:
A method for processing a signal, comprising: receiving a signal having an analog form; sampling the received signal in the analog form at one or more sampling times to yield one or more sampled signals, each sampled signal having an analog form; repeating the following for each sampled signal of the one or more sampled signals: generating a feedback signal from the sampled signal, the feedback signal having a digital form; converting the feedback signal from the digital form to an analog form; determining correlation associated with the sampled signal according to one or more feedback signals in the analog form generated from the one or more sampled signals; and adjusting the sampled signal having the analog form in accordance with the correlation associated with the sampled signal in order to process the received signal; and repeating the following for each sampled signal of the one or more sampled signals: filtering pre-cursor interference from the received signal in accordance with an error determined using the feedback signal having the analog form.
