Summary:PURPOSE: A decoder and a decoding method using orthogonal space-time block codes are provided to prevent the degradation of performance by combining channel state information in the transmitting period of block codes. CONSTITUTION: A periodic preamble code eliminating part(210) eliminates a periodic preamble code from a received signal. An inverse discrete Fourier converting part(220) applies an inverse discrete Fourier conversion to a signal without the periodic preamble code. A protective band eliminating part(230) generates a complex matrix by eliminating the protective band from the inverse discrete Fourier converted signal. A channel estimating part(250) provides channel state information with respect to a transmitting and receiving antenna and carrier corresponding to the complex matrix.
