This paper proposes a blind channel estimation scheme for long code DS-CDMA systems with multipath fading channel. The Toeplitz displacement method is used to remove the effects of channel noise and interferences before the correlation matching approach is adopted to estimate the channel parameters. Simulation results show that the proposed method has better MSE performance and more robust against the near-far problem.
