The synchronous signal is shuffled to increase randomness or whiten the spectrum of the transmitted signal sequence. The synchronous scrambler uses an additive linear feedback shift register (LFSR). This paper uses an effective mathematical tool to describe Pseudo-random Noise-PN, which is finite field theory, and D transform, then develops an algorithm to generate pseudo-random sequences to implement a synchronized signal scrambler. Simulations are performed for some specific cases for two pseudo-random sequences m corresponding to polynomials of order 8 from which the sequence is determined after signal scrambling. Signal mixing can use m-series corresponding to higher-order polynomials.
