Abstract :
The pre-coded STBC transmission is an effective scheme in order to improve performance of OFDM under frequency selective fading channels. However, its performance degrades very severe frequency selective fading. In this paper, an iterative detection scheme of the pre-coded STBC OFDM scheme is proposed and good performance is confirmed by computer simulation.
