A new blind method is proposed for identification of CDMA Time-Varying (TV)channels in this paper. By representing the TV channel’s impulse responses in the delay-Dopplerspread domain, the discrete-time canonical model of CDMA-TV systems is developed and asubspace method to identify blindly the Time-Invariant (TI) coordinates is proposed. Unlikeexisting basis expansion methods, this new algorithm does not require estimation of the base
