    Abstract: PROBLEM TO BE SOLVED: To reduce time required for automatic gain control in a rough adjustment of an automatic gain control process.SOLUTION: A first frequency conversion section generates an I system baseband signal from a high frequency received signal and a first local signal in a predetermined frequency band. A second frequency conversion section generates a Q system baseband signal from the high frequency received signal and a second local signal out of phase by 90° with the first local signal. First and second variable amplification sections amplify the generated I and Q system baseband signals, respectively. First and second AD conversion sections convert the amplified I and Q system baseband signals to digital data, respectively. First and second over-range detection sections detect over-ranges of the first and second AD conversion sections. An automatic gain control section selects a gain on the basis of detection information about the over-ranges, and the I and Q system baseband signals. An offset setting section gives a predetermined offset to the selected gain, and sets the offset gain to the first or second variable amplification section.

    Abstract: PROBLEM TO BE SOLVED: To accurately correct passband characteristics without an increase in circuit scale, even for baseband signals having a signal bandwidth that spans a wide band as a result of a high-speed symbol rate.SOLUTION: During transmission, a symbol sequence that has been modulated using a symbol rate fs(Hz) from a modulation unit 103 is input, and then converted into a parallel signal every N symbols in a serial/parallel conversion unit 109. The N symbol signal undergoes a Fourier transform in an N-point Fourier/inverse Fourier transform unit 108, and is converted into an N-point frequency domain signal. The N-point signal bandwidth is widened to P×N points. For each frequency bin, a correction coefficient multiplication unit 106 multiplies the frequency domain signal having the bandwidth widened to P×N points by a transmission distortion correction coefficient obtained in a correction coefficient calculation unit 107. The P×N-point frequency domain signal that has been multiplied by the transmission distortion correction coefficient undergoes an inverse Fourier transform in a PN-point inverse Fourier/Fourier transform unit 105 and is converted into a time axis signal.
