Abstract :
The realization of wireless communication providing high speed, high capacity and high quality information exchange between two portable terminals that might be located anywhere in the world is still the communication challenge. For the development of future wireless communication systems, an extremely spectrum-efficient transmission technology is required. In this paper, we interface OFDM with CDMA and then integrate this CDMA-OFDM to MIMO to generate a system which is functionally superior to other multicarrier systems. We investigate the effect of multipath signal propagation on the capacity, under both single and multi user channel on the conventional MIMO, MIMO-OFDM and spread MIMO-OFDM. The obtained results show that the multipath signal propagation has more influence on the capacity of MIMO than MIMO-OFDM and spread MIMO-OFDM. In addition, the capacity of spread MIMO-OFDM is higher under the condition of the multi user channel scenario. Finally we implement the CDMA-OFDM-MIMO technology as an integrated system taking all the desirable qualities of these system architectures, thus yielding a very robust and strong system. Therefore, Hybrid technology can offer a very powerful and affordable solution for real life wideband multimedia system targeting Giga-bit speed wireless transmission and ITS applications.
