A linear autocorrelator for synchronization of binary coded messages
Vernon Jennings, G. E. Miller · IEEE Transactions on Communication and Electronics · 1963
RELIABLE SYNCHRONIZATION is one of the major problems encountered in digital data transmission systems. One method by which the synchronization reliability may be improved is to increase the length of the synchronization word, particularly if Barker or other optimum words are employed. The full theoretical improvement offered by the use of such a word can be approached in practice only if the word is recognized as an ensemble by a device which processes the combination of signal and noise as a linear mixture.
