In this paper, a space-time block-coded (STBC) multicarrier direct-sequence code-division multiple access (MC-DS-CDMA) system is proposed. The performance of the system is theoretically analyzed in a multipath fading channel and the corresponding BER expressions are derived, which is verified through simulations. Numerical results show that better performance with the proposed system is achieved than that of conventional MC-DS-CDMA system
