摘要：
This paper proposes Steepest Decreasing Constant Modulus Algorithm (SDCMA) detection in fre-quency domain for MultiCarrier Direct Sequence-Code Division Multiple Access (MC DS-CDMA) systems. The proposed algorithm is used to equalize independent fadings of all subcarriers. At the same time we com-pare the SDCMA blind detection with subspace-based Minimum Mean-Squared Error (MMSE) detection. The simulation results show that the performance of SDCMA blind detection is superior to that of subspace-based MMSE detection and the complexity of the former is much lower than that of the latter.
