BER of Alamouti STBC MC-CDMA with Imperfect Channel State Information
In this paper, we study the effect of channel estimation errors for the multiple input multiple output (MIMO) multi-carrier code division multiple access (MC-CDMA) system. The performance of Alamouti Space Time Block Code (STBC) together with MC-CDMA is derived by using moment generating functions (MGF) method. Finally, the closed form of bit error rate (BER) expression is presented. Without loss of generality, the scheme of two transmitting antennas and one receiving antenna is proposed, which could be straightforwardly extended to the more general cases. In the case of imperfect channel estimation, the simulation results demonstrate the BER performance for the MIMO MC-CDMA system is greatly depending on the errors in the channel estimation.
