On achieving frame synchronization in guided scrambling line codes

We present a framing method for the guided scrambling (GS) line code. It is modeled using a random walk with a reflecting barrier at one end and an absorption barrier at the other. The method is based on the statistical analysis of the encoded data stream. Results for a (3,4) block GS scheme are presented which compare in-frame and out-of-frame values for the mean time to absorption in order to demonstrate the validity the chosen framing method.
