Method for reducing interference shared channel.

The present invention concerns a communications procedure where AVOID THE SAME invention allows ADVANCE THE RESTORATION Erroneous a series of signals that are sent in other communication, EVEN WHEN USING THE SAME CHANNEL other communication. A Orthogonal Matrix, different for each communication is multiplied by the series of signals and sent, and the series of signals before conversion Orthogonal is restored by multiplying the inverse matrix conversion Orthogonal, WHICH IS USED ON THE SIDE ISSUING OF SOCIO of communication, signals received SERIES, sO other communication is performed using the same channel. EVEN WHEN RECEIVING other communication, the series of signals sent in the other communication is not restored, including scaling inverse matrix, BECAUSE OF THE MATRIX Orthogonal USED IN THE CONVERSION Orthogonal DIFFERENT FROM OTHER COMMUNICATIONS.
