A digital modulation scheme, OFDM, multiplexes many orthogonaly arranged sub-carriers and use spectrum efficiently. However, its performance is degraded under environments with severe multipath fading. The use of a previously reported, iterative detection of pre-coded OFDM scheme is proposed. Furthermore, the results of a computer simulation confirmed good performance. We present our analysis of the performance of iterative detection of pre-coded OFDM combined with convolutional code. The results of the simulation show that our scheme, performed better under severe fading than the conventional scheme did.
