Abstract:
1. A method for recovering data from a data signal, comprising: oversampling the data signal with reference to a sample parameter to provide a plurality of sample sets, the sample sets including samples of respective data symbols; modifying sample sets in the plurality of sample sets by adjusting transition positions within a sample set, to provide modified sample sets; storing the plurality of sample sets including the modified sample sets in memory; sequentially processing in response to a sequential logic clock, sample sets in the plurality of sample sets including the modified sample sets to make, in more than one cycle of the sequential logic clock, determinations of respective subsets for particular sample sets in the plurality of sample sets including the modified sample sets, the respective subsets including one or more samples suitable for use in data recovery, said determination being a function of the samples in more than two sample sets; and obtaining the respective subsets for the plurality of sample sets including the modified sample sets from the memory for recovering data.
