摘要:	In this paper, the detection problem of DS-CDMA systems is transformed to an equivalent problem of beamforming systems by the multirate signal processing technique. In this situation, the channel plus spreading code in DS-CDMA systems is represented by an equivalent steering matrix in the signal processing of beamforming systems. An optimum detection design based on optimum beamforming technique is proposed for DS-CDMA systems. Furthermore, stochastic processes model the time-varying tap coefficients of multipath fading channel. The channel parameter or steering matrix estimation algorithm is developed using the Kalman state estimation method. Because the dynamics of multipath fading channel is considered in the design procedure, the proposed design method possesses better tracking ability of multipath fading channel than that of the conventional adaptive methods. Finally, an adaptive detection design for DS-CDMA systems is also discussed in this paper. Several simulation results are also given to illustrate the performance of the proposed method.
