Abstract: An Orthogonal Frequency Division Multiplexing (OFDM) system with spacctimc coding Interleave Division Multiplexing (IDM) was investigated over a Multi-Input Single-Output(MISO) link.The performance of an iterative receiber structure for the proposed scheme over a quasi-static channel was evaluated via simulation.and its advantages were shown by comparison to other space-time schemes in similar settings.

Key words: IDM, MIMO, OFDM, Spacetime coding, Iterative decoding
