摘要
An apparatus and method for obtaining synchronization of a maximum length pseudorandom sequence included within input data. The apparatus comprises means for generating a predicted pseudorandom sequence, means for comparing the pseudorandom sequence with the input data and means for determining from said comparison whether said predicted pseudorandom sequence and said input data are the same. The method employed is a bit-by-bit comparison between the predicted values of a predicted pseudorandom sequence and the incoming values of the input data, synchronization is indicated when a predetermined number of successive comparisons are obtained, where said predetermined number of successive comparisons is less in number than the maximum length of the specified maximum length pseudorandom sequence.
