Claim Text:
1. A receiving device comprising: circuitry configured to accumulate the second preamble signal when the first preamble signal is detected; process the data signal based on the control information contained in the second preamble signal accumulated, the data signal being contained in the same frame as the second preamble signal accumulated; correct a detected carrier frequency error contained in the frame signal; estimate a guard interval (GI) length of the symbols forming the corrected frame signal based on part of the frame signal; determine the data amount of the P2 symbol based on a Fast Fourier Transform (FFT) size indicated by information contained in the P1 symbol and the GI length estimated by the circuitry; and read a signal having the determined data amount as the signal of the P2 symbol.
