FIELD: communication.SUBSTANCE: invention relates to communication engineering and can be used to transmit signals. Signal transmission method includes steps of establishing virtual users, each of which is connected to one base station, preliminary code of base station and user code corresponding to each of the virtual users are obtained, baseband signal is divided onto virtual users and baseband divided signal corresponding to each of K virtual users, divided baseband signal is processed and uplink signal is obtained corresponding to each virtual user, signal is transmitted to base station.EFFECT: technical result is performance of controllability of interference between uplink signals from different users and high efficiency of uplink signal transmitting by user terminal.19 cl, 12 dwg |
