Abstract :
MIMO-OFDM systems would provide both multiplexing gain and diversity gain in order to improve the system capacity and the receive performance. This paper introduces the coordinate interleaved hybrid transmission for use in MIMO- OFDM systems to meet such requirements. The proposed CID- SFBC-OFDM and CID-STBC-OFDM combine the coordinate interleaver with Double SFBC-OFDM and Double STBC-OFDM to achieve additional diversity gain whilst retaining their spatial multiplexing gain. Our simulation results show that CID-SFBC- OFDM and CID-STBC-OFDM outperform the conventional schemes in typical urban (TU) channel.
