  Abstract

In tins paper we design STBC-OFDM systems by applying several STBC schemes to the OFDM system and show their comparative analysis results obtained through computer simulations under Rayleigh fading environments, considering the effect of channel estimation error. We first consider the space-time coding algonthms of major STBC schemes, together With their demodulation algonthms We then select the OFDM parameters considering mobile environments and design the STBC-OFDM systems by choosing one of digital modulation schemes such as QPSK, 8PSK, 16QAM, 64QAM, and 256QAM according to the transmission rate, and describe the block diagrams of the demodulator and charmel estrmator We finally compare and analyze the BER performances of the STBC-OFDM systems according to the transmission rate and the number of receive antennas
