    摘要: A transmission apparatus, including an error correction code calculation section adapted to calculate an error correction code from data of a transmission object as an information word is disclosed. The transmission apparatus further includes a division section adapted to allocate coded data which configures a codeword obtained by adding the error correction code determined by the calculation by the error correction code calculation section to the data of the transmission object for each predetermined number of units to a plurality of transmission lines. The transmission apparatus further includes a plurality of transmission sections provided corresponding to the plural transmission lines and adapted to transmit the coded data allocated by the division section to a reception apparatus through the transmission lines.

    摘要: An OFDM demodulation (1) is provided which includes a guard correlation/peak time detection circuit (12) to generate a peak timing Np of a guard interval correlation value, and a timing synchronization circuit (13) to estimate a symbol-boundary time Nx from the peak timing Np. The timing synchronization circuit (13) calculates the symbol-boundary time Nx by filtering the peak time Np by a DLL (delay locked loop) filter (43). Further, the DLL filter (43) includes a limiter (52) to limit the range of phase-error component and an asymmetric gain circuit (53) to change the magnitude of the gain correspondingly to the polarity of the phase error to prevent the timing from being pulled out due to a fading or multipath.
