Abstract
The Big Viterbi Decoder (BVD), currently under development for the Deep Space Network (DSN), uses three separate algorithms to acquire and maintain node and frame synchronization. The first measures the number of decoded bits between two consecutive renormalization operations (renorm rate), the second detects the presence of the frame marker in the decoded bit stream (bit correlation), while the third searches for an encoded version of the frame marker in the encoded input stream (symbol correlation). This article gives a detailed account of the operation, as well as an evaluation of performance, of the third scheme.
