Abstract
Demodulator assembly for m data trains, with differential phase modulation, comprising, for each train, an elementary demodulator dimensioned over a space of one bit, whereas the coding is effected over a space of n intermediate bits, comprising, for each train, a shift register having n+1 flip-flops in a functional connection with an adder.
Claims5
A demodulator assembly for m differential phase shift modulation trains, in which the phase shift information concerns bits spaced by n intermediate bits, said assembly comprising:
- for each train elementary demodulator means for providing bit signals relating to phase differences of adjacent bits, shift register means for receiving respective outputs of said demodulator means, said shift register means being provided with n+1 flip-flops, and adder means connected to said shift register means to receive at n+1 bit informations contained in said n+1 flip-flops for producing a respective one of m demodulated output trains being dephased between bits spaced by n intermediate bits.
