Multiuser code acquisition system based on Interference Cancellation (IC) is proposed for the reverse link of base station of Direct Sequence Code Division Multiple Access (DSKDMA) systems. Explicit expressions for the variance and density function of correlator output are derived incorporating data and timing estimation errors. Consequently, a threshold rule based on a posteriori probability can be applied which guarantees an upper bound on acquisition error probability beforehand, a very important system performance criterion. Computer simulation results show that acquisition error probability is below the upper limit; system capacity and mean acquisition time performance are also promising.
