Abstract :
We design STBC-OFDM systems with multiple-input multiple-output (MIMO) by applying several STBC schemes to the OFDM system and show their comparative analysis results obtained with the various mobile speeds, under Rayleigh fading environments, considering the effects of channel estimation error. There is no systematic comparative analysis for those STBC techniques, considering the 4th generation mobile system environments with various mobile speeds. Therefore it is very important to derive the optimum STBC-OFDM for 4G mobile system environments. We finally compare and analyze the BER performances of the STBC-OFDM systems according to the mobile speeds and the number of antennas.
