Systems and methods for dibit correction
Various embodiments of the present invention provide systems and methods for providing a corrected dibit signal. As an example, various embodiments of the present invention provide dibit correction circuits. Such dibit correction circuits include a dibit sample buffer, a maximum sample detector circuit, a side sample detector circuit, and a dibit correction circuit. The dibit sample buffer includes a plurality of samples of an uncorrected dibit signal. The maximum sample detector circuit identifies a maximum sample of the plurality of samples of the uncorrected dibit signal, and the side sample detector circuit identifies a first side sample prior to the maximum sample on the uncorrected dibit signal and a second side sample following the maximum sample on the uncorrected dibit signal. The dibit correction circuit applies a correction factor calculated based at least in part on the maximum sample, the first side sample and the second side sample to at least a subset of the plurality of samples of the uncorrected dibit signals to yield a plurality of corrected dibit signals.
