Abstract:
1. A method of detecting transmit data symbols X 0;m , . . . , X A−1;m in an STBC-OFDM communication system in which A transmit data symbols X 0;m , . . . , X A−1;m are STBC encoded and OFDM modulated during B OFDM symbol periods for each sub-channel m (m=0, 1, . . . , N−1) and are then transmitted through P (P>1) transmit antennas, comprising: a step of demodulating STBC-OFDM modulation signals into Y a step of estimating frequency responses H an STBC decoding step of calculating decision variables R a step of determining the transmit data symbols X wherein the STBC decoding step calculating the decision variables R
