  • In this paper, a Space-Time Block-Coded MultiCarrier Direct-Sequence Code-Division Multiple-Access (STBC MC-DS-CDMA) system is proposed. By constructing the unified signal model of STBC MC-DS-CDMA system, the subspace-based blind channel estimation is achieved and its efficiency is shown by simulation results. Based on the estimation results, consequently, the Minimum Mean-Squared Error (MMSE) multiuser detection for the STBC MC-DS-CDMA is also realized which improves the system performance significantly.
