US Patent 7339990 Processing a received signal at a detection circuit

Processing a received signal includes receiving a signal having an analog form. The signal is sampled to yield sampled signals having an analog form. The following are repeated for each sampled signal. A feedback signal is generated from the sampled signal, and is converted from a digital form to an analog form. Correlation associated with the sampled signal is determined according to feedback signals generated from the sampled signals. The sampled signal having the analog form is adjusted in accordance with the correlation associated with the sampled signal in order to process the received signal.
