The method comprises: according to the time delay of the enabled user of the accessed OPDMA uplink receiver and the frequency deviation information, generating an interference matrix; receiving the users' signals from the enabled user, and partitioning the received signals into blocks; applying the interference matrix on each block; OFDM demodulates the received users' signals and discards the unused subcarriers. The invention also comprises: applying the factoring matrix, formed by the correction matrix generated from the interference matrix through factoring, on the users' signal blocks; and forming an inverse matrix based on the factoring.
