ABSTRACT:
Transmission process having spectrum spread phase differential modulation and demodulation using orthogonal pseudorandom sequences. Use is made of two orthogonal pseudorandom sequences (C.sub.E1, C.sub.E2) for spreading the spectrum of the symbols (d.sub.k) to be transmitted and detection takes place of the phase difference between the received signals filtered by filters matched to the two sequences, one being delayed.
