PCT No. PCT/EP90/01666 Sec. 371 Date Jul. 29, 1991 Sec. 102(e) Date Jul. 29, 1991 PCT Filed Oct. 10, 1990 PCT Pub. No. WO91/06155 PCT Pub. Date May 2, 1991.The spread-spectrum signal (S1) is converted into a one-bit quantized binary signal (S2) and this signal is coupled to a plurality of parallel detection circuits (10), each of said detection circuits being adapted to detect a distinct code epoch. Each detection circuit (10) receives concurrently a shifted version of a binary reference code (CR) and produces a signal (B3) having a first binary state when the received signal corresponds to the code epoch of the detection circuit and having a second binary state should it be otherwise. The output signals (B3) are combined and/or encoded to identify the correct code epoch in order to demodulate the received signal. The invention is used in communication systems receivers.
