Blind identification of CDMA time-varying dispersive channels based on first-order statistcs
Tianxiang Gu · Chinese Journal of Radio Science · 2007
Based on the discrete-time canonical model,a new blind identification approach for CDMA time-varying dispersive channels is proposed.With the first-order statistics of the time-frequency decorrelating receiver output,the channel parameter is estimated.The appraoch has lower complexity of computation and need less observations than that of usual blind identification approaches.Simulation results illustrate the effectiveness of the proposed appraoch.
