Abstract

A communication method comprise an space-time block code(STBC)-processing step for dividing a transmit symbol sequence X into blocks and generating two mutually orthogonal symbol sequences XnA and XnB based on a symbol sequence Xn of each block, a transmitting step for modulating each of the symbol sequences XnA and XnB by an OFDM system and transmitting it by a transmitter diversity system; an OFDM demodulating step for demodulating a receive signal by applying discrete Fourier transform thereto, and generating a receive symbol sequence Rn, and an STBC demodulating step for demodulating a symbol sequence Xn' of each block by using a receive symbol sequence Rn for inverse matrix H-1 of transfer function matrix H, constituted based on a transfer function estimated for each block and for each sub-carrier by a prescribed estimation method, and by which the receive symbol sequence Rn is related to the symbol sequence Xn.
