Abstract:
1. A transmission-reception device, comprising: a radio frequency section that performs a frequency conversion on a signal which is modulated using a single carrier transmission system; a correction coefficient multiplier that multiplies a frequency domain signal by a distortion correction coefficient in the frequency conversion of the radio frequency section to correct a distortion; a first transformer that converts a time domain signal into a frequency domain signal at a time of reception, and converts the frequency domain signal which is distortion-corrected by the correction coefficient multiplier into a time domain signal at a time of transmission; and a second transformer that converts a time domain signal into a frequency domain signal at a time of transmission, and converts the frequency domain signal which is distortion-corrected by the correction coefficient multiplier into a time domain signal at a time of reception; wherein the correction coefficient multiplier corrects transmission distortion characteristics in a transmission side of the radio frequency section at the time of transmission, and corrects reception distortion characteristics in the reception side of the radio frequency section and channel distortion characteristics at the time of reception.
