METHOD FOR INTERFERENCE CANCELATION IN MOBILE COMMUNICATION SYSTEM

摘要

A method for removing an inter-carrier interference in a mobile communication system is provided to remove an inter-carrier interference by reducing a frequency offset according to a channel state. A transmitting part generates a control signal(S101). The transmitting part transmits a control signal through a wireless channel(S103). A receiving part checks a generating state of a frequency offset of the received control signal(S105). The receiving part estimates a channel state and a SNR(Signal to Noise Ratio)(S107). The receiving part generates feedback information including a channel quality indicator corresponding to the estimated channel state and the SNR(S109). The receiving part transmits the feedback information to the transmitting part through a wireless channel(S111). The transmitting part predicts a channel state about the wireless channel(S113). The transmitting part generates an OFDM(Orthogonal Frequency Division Multiplexing) signal(S115). The transmitting part transmits the OFDM signal to the receiving part(S117). The transmitting part determines an excessive state of a coherence time(S119). The transmitting part checks an additional transmission(S121).
