Frame synchronization using distributed sequences

Frame synchronization is traditionally achieved by inserting a given sequen ce periodically into the data stream. Here, a new method of synchronization is introduced in which the synchronization sequence is not contiguous, but is interleaved with the data symbols. The properties of these distributed sequences are investigated, and requirements are specified for detectibilit y of these sequences when inserted in random data. Methods for constructing and searching for good sequences are presented. It is demonstrated that th is new method reduces the probability of false synchronization over traditi onal methods in the presence of additive white Gaussian noise.
