Abstract
This paper describes a practical frame synchronization (sync) acquisition and maintenance algorithm based on the Hamming distance metric, which is a generalization of the scheme developed for the 1973 Mariner mission to Venus and Mercury (MVM’73). For the special case of uncoded phase-shift-keyed data received over the binary symmetric channel, formulas are derived for computing an upper bound on the probability of false sync acquisition, the mean time to sync acquisition, and the mean time to the subsequent loss of sync, as a function of the bit error rate, frame length, sync word length, and algorithm parameters. These formulas are directly applicable to the uncoded MVM’73 telemetry modes, and a numerical example relating to the 117.6 kilobits/s real time TV mode is included.
