Abstract
A state synchronized cipher text scrambler is disclosed. The state synchronized cipher text scrambler enables multiple data streams to be scrambled in parallel in such a way that the data streams are uncorrelated with respect to each other and there is a large fixed delay relationship between the scrambler bits over the multiple streams. This enables a receiver to correctly identify the ordering of the multiple data streams with respect to each other automatically, correct for any polarity or wire-swap misconnections and align the received multiple data streams despite differential delays between the data streams.
