Decoder and decoding method using orthogonal space-time block codes robust to timing errors

It discloses a decoding apparatus and method using a robust orthogonal space-time block code in the timing error. Decryption device using the Robust orthogonal space-time block code in a timing error of the received signal, and cyclic permutation code remover for removing a cyclic permutation code in a received signal; Said cyclic permutation discrete Fourier transform unit for code applies a discrete Fourier transform on the removed signal; Guard band remover for generating a complex matrix by removing a guard band in the discrete Fourier transform signal is applied; A channel estimator for providing channel state information for the carrier and the transmitting and receiving antenna corresponding to the complex matrix; And to calculate the channel state vector for the complex symbols contained with all the channel state information to the complex matrix, and calculating the dot product between the channel state vector and the complex matrix comprising a decoding to restore the complex symbols. Orthogonal space-time block code, a complex symbol, timing, error, OFDM.
