Provided is an apparatus and method for decoding orthogonal space-time block codes (OSTBCs), which are robust against timing errors, The decoding apparatus may include: a cyclic prefix removal unit; an inverse discrete Fourier transform (IDFT) unit; a guard band removal unit which generates a complex matrix; a channel estimation unit to transmit a carrier corresponding to the complex matrix and channel status information associated with transmit and receive antennas; and a decoder to calculate a channel status vector with respect to a complex symbol included in the complex matrix, using the channel status information, and to calculate the inner product of the channel status vector and the complex matrix, to restore the complex symbol. |
