A turbo encoding section 102 turbo-encodes transmission data, outputs systematic bit data to a first modulation section 103a and outputs parity bit data to a second modulation section 104. The first modulation section 103a always QPSK-modulates systematic bit data. The second modulation section 103b adaptively modulates parity bit data. The control section 101 outputs a control signal for carrying out 16 QAM modulation to the second modulation section 103b when the RSSI value is equal to or higher than a threshold and outputs a control signal for carrying out QPSK modulation to the second modulation section 103b when the RSSI signal value is less than the threshold. In this way, it is possible to further make the error rate characteristic compatible with the transmission efficiency. |
