摘要： An FFT unit subjects a P-times oversampling output of an AD converter to Fourier transform into a frequency domain signal. A distortion estimation unit estimates a distortion characteristic from a difference between the frequency domain signal and a reference signal. A correction coefficient calculation unit calculates a correction coefficient of a distortion characteristic. A correction unit corrects the frequency domain signal by using the correction coefficient. An IFFT unit subjects the corrected frequency domain signal to inverse Fourier into a time domain signal having the same sampling speed as a symbol speed, and outputs a partial time series.

摘要： A demodulation section demodulates a received signal. A decoding section decodes an output from the demodulation section. A buffer temporarily stores a portion of the received signal. A header analyzing section gives the buffer timing at which demodulation and decoding of a payload of the received signal are initiated, on the basis of a result of combination of a plurality of header sequences included in a header of the received signal and results of processing of the demodulation section and the decoding section. An improved SNR is achieved by means of combination of the plurality of header sequences, so that an iterative decoding count used for decoding the header become smaller.

摘要： An AGC unit starts a gain control of the variable gain amplifying unit when a bit saturation occurs in the digital baseband signal output from the A/D converting unit, and starts a gain control of the variable gain amplifying unit when a detection of STS from the digital baseband signal output from the A/D converting unit is started. The AGC unit performs the gain control of the variable gain amplifying unit once when the detection of STS is started, and performs the gain control of the variable gain amplifying unit twice when the bit saturation occurs, namely a larger number of times than when the detection of STS is started.
