Introduction to Frame Synchronous Scrambling
Frame synchronous scrambling (FSS) is a scrambling technique which employs SRGs generating PRBSs for use in scrambling as well as in descrambling of the data bitstream. For the synchronization of the SRGs it resets the SRG states to some prespecified states at every frame start. Due to this resetting operation, FSS is suitable for scrambling of framed signals, and the scrambling effect is better for larger-sized frames.
