Scramblers and shift register generators (SRG) have been used for
decades in the shaping of digital transmission signals and in generating
pseudo-random binary sequences for transmission applications. In recent
years more attention has been paid to this area than ever before due to
the change of today's telecommunication environment. This publication
presents the theory and applications of three scrambling techniques -
Frame Synchronous Scrambling (FSS), Distributed Sample Scrambling (DSS)
and Self Synchronous Scrambling (SSS) with an emphasis on their
application in digital transmission. Based on the authors' research over
the past ten years, this is the first book of its kind.
