%X In MIMO DS/CDMA systems, the different transmit/receive antenna pairs have different frequency offset, which increases the complexity of the frequency offset estimating. Based on the cyclostationarity of the signal, a blind frequency offset estimating is proposed in this paper. The advantages of the estimating are: (1) It can separately estimate the frequency offset of the different antenna pair; (2) It is a blind estimator and does not need training sequence which lower the efficiency of the wireless bandwidth; (3) It can fully utilize the cyclic correlation of the received signal at all nonzero cyclic frequency. The simulation results provided in this paper show that the estimating has good performance in the FIR channel environment.
