Patent ID: 8644404

Claim:
A wireless communication system performing wireless communication between a transmitter device and a receiver device according to a multicarrier multiplexing transmission method, said wireless communication system characterized in that the transmitter device performs error-correction coding on transmitting data and sets a plurality of null subcarriers, having zero amplitude, among a plurality of subcarriers, which are allocated to transmission of data produced by error-correction coding so as to configure each transmission frame set for each time slot, in accordance with a predetermined null pattern facilitating estimation of an interference wave, thus transmitting all data produced by the error-correction coding via the plurality of subcarriers without decreasing transmission speed, while the receiver device performs error-correction decoding on received signals from the transmitter device so as to reproduce the transmitting data, wherein upon detecting reception power exceeding a threshold in the null subcarrier for each transmission frame, the receiver device determines that an interference wave occurs in the transmission frame.
