摘要： The present invention presents fully noncausal predictive encoding and decoding methods for image, video and other signal coding. The presented noncausal predictive image coding methods largely reduce the prohibitive computational cost of the prior invention. The presented noncausal signal encoding method comprises: (1) splitting the source signal into a plurality of noncausal coding units; (2) extending each noncausal coding unit with the selected extension type; and (3) encoding each noncausal coding unit with the selected intra-unit noncausal predictor and intra-unit noncausal predictive encoding method.

摘要： An automatic gain control (“AGC”) system. The system includes a first multiplier, an envelope detector, a summation module, a filter module, a convergence module, and a feedback module. The convergence module includes a convergence control module and a second multiplier. The feedback module includes an accumulator, a scalar multiplier module, and a third multiplier.

摘要： A method of controlling a digital demodulator (922) coupled to an equalizer (930) includes the steps of generating an equalizer value (930A), filtering (944) the equalizer value (930A) to obtain a post filter output, subtracting the equalizer output signal (930C) from the decoded data (930D) and generating an error value (924A). The post filter output is correlated (948) with the error value (924A) to obtain a correlated value (74A). A control signal is developed from the correlated value and is used to adjust the digital demodulator (922).
