1. A data transmission system comprising:

  • a transmission part producing a copy of a given narrow-band signal so as to obtain a number of identical signals according to a predetermined orthogonal sequence, and performing respective phase rotations on the thus-obtained signals according to the predetermined orthogonal sequence; and

    a reception part performing reverse phase rotation on the reception signals according to the predetermined orthogonal sequence, and then performing mutual addition thereon so as to restore the narrow-band signal.
