Provided are a processing method and communication device based on an OFDM-TDMA two-way service. The method comprises: by means of a TDMA mode, assigning the timeslots in a TDMA frame structure to a plurality of users, so that the timeslots of each user are different from one another, and the timeslots of each user are used for uplink and downlink at the same time; over each user timeslot, transmitting a near-end OFDM signal and receiving a far-end OFDM signal at the same time; and by means of an OSD mode, eliminating the interference of an echo OFDM signal generated by the near-end OFDM signal on the far-end OFDM signal, wherein the frequency spectrum of the echo OFDM signal is superposed with the frequency spectrum of the far-end OFDM signal. |
