WebMultiplicative (self-synchronizing) scramblers Additive (synchronous) scramblers An additive scrambler (descrambler) used in DVB Additive scramblers (they are also referred to as synchronous) transform the input data stream by applying a pseudo-random binary sequence (PRBS) (by modulo-two addition). WebA self-synchronizing scrambler for high bit rates comprises a plurality of scrambler stages operating in parallel and which respectively represent the series connection of a first modulo-2 adder and a second modulo-2 adder and a shift register stage, whereby the output of the shift register stage is fed back to the input of the first modulo-2 adder of its own …

WebA self-synchronizing scrambler/descrambler arrangement operates in two modes. In the first, or start-up mode, predetermined data is coupled to the scrambler and transmitted to … WebIn the SSS, the states of the scrambler and descrambler shift registers are automatically synchronized without any additional synchronization process. Scrambling effect of the SSS is good in general, but a bit error in the scrambled bitstream can …
