Abstract :
Multiple-input multiple-output MC-CDMA systems receive a great deal of attention due to their great potential in achieving high data rates in wireless communications. Nevertheless, performance of MIMO MC-CDMA systems can severely degrade due to inaccurate channel estimation especially over frequency-selective fast-varying channels. In this paper, we address a MIMO MC-CDMA coherent transmission with a pilot aided turbo channel estimation improved by addition of a linear regression algorithm included in an iterative receiver. The efficiency of the proposed channel estimation is demonstrated over fast time varying channels
