| Abstract(in English) | New types of spatial channel estimation techniques for the blind sigle-user space-time CDMA receiver are considered. We propose two spatial channel estimation techniques using Power Method (PM) : Covariace Method (CM) in which the data covariance matrix of the despread array output is applied to the PM and Decision-directed and Differentially-formed Covariance matrix-based Method (DDCM) which utilizes the decision feed-back from the time domain filter with differentially formed covariamce matrix of the array output to estimate the effective interference-free covariace matrix of the spatial channel. The simulation results shows the DDCM can enhance the BER performance of the resulting space-time receiver in the Rayleigh fading channel in the "near-far" situation. |
