%X This paper deals with pilot-based channel estimation of space-time coded OFDM system in frequency selective channels. DFT-based LS and LMMSE method are studied. A practical channel estimation method is proposed. In proposed method the complexity of LS and LMMSE methods is greatly reduced by optimally designing the pilot symbols. And the performance demonstrated by simulation is close to idea channel information.
