DECODER AND DECODING METHOD USING ORTHOGONAL SPACE-TIME BLOCK CODES ROBUST TO TIMING ERRORS

摘要

The decoding apparatus and method for timing error with a robust orthogonal space-time block code is disclosed. Robust orthogonal decoding device using the space time block code in a timing error, receiving the signal, the received cyclic permutation code remover for removing a cyclic permutation code in the signal; A discrete Fourier transform unit for applying a discrete Fourier transform on the periodic permutation code signal has been removed; Guard band remover for removing a guard band in the discrete Fourier transform is applied to the signal to generate a complex matrix; A channel estimator for providing channel state information on the carrier wave and transmitting and receiving antenna corresponding to the complex matrix; And using the channel state information and calculate all the channel state vector for the complex symbols contained in the complex matrix, calculating the inner product between the vector and the complex channel state matrix includes a decoder which restores the complex symbols.
