摘要： Asynchronous sampling digital detection (ASDD) methods and apparatus are described. In one embodiment, noise-corrupted information is received and comprises a plurality of information-carrying events which encode binary information which is desired to be retrieved. A plurality of values are extracted from the noise-corrupted information-carrying events which are representative of the encoded binary information. An amount of noise corruption carried by one of these plurality of values is estimated by considering an amount of noise corruption carried by another of the plurality of values. Responsive to the estimation of the noise corruption, the one value is then modified. In another embodiment, noise-corrupted information is received comprising a plurality of information-carrying events which encode binary information which is desired to be retrieved. A plurality of values from the noise-corrupted information-carrying events are determined which are representative of the encoded binary information. A set of conditions is defined which are a function of the plurality of values, and which have value-dependent outcomes. For a given determined value of the plurality of values, a value-dependent outcome is imposed to produce at least two intermediate noise-adjusted values. Using the two intermediate noise-adjusted values, a noise-reduced output value for the given determined value is selected.
