A communications system includes a primary station having transmitting and receiving sections, a formatting stage for formatting messages to be transmitted by the transmitting section, and one or more secondary stations. The or each secondary station has a receiving section for receiving messages from the primary station and a transmitting section for transmitting signals as pseudo-random code sequence signals, and the primary station is adapted to receive and to simultaneously decode and detect the or each of the pseudo-random code sequence signals. The simultaneously decoding and detection operations involves implementation of a Fast Fourier Transform (FFT) in a manner that a code sequence for despreading the pseudo-random code sequence is applied within the FFT. A resulting spectrum is checked for a peak which indicates that one of the pseudo-random code sequences has been successfully decoded and detected.
