A new blind identification method for DS-CDMA systems with antennaarray under multipath fading

摘要

In recent years, some blind adaptive multiuser detectors have beennpresented to implement multiuser detection with only the knowledge ofnthe desired user's spreading code and propagation delay. We find, innthis paper, that with the aid of the antenna array, multiuser detectionncan be achieved even without the desired user's spreading code andnpropagation delay, provided that the direction of arrival of every usernis different from each other. Propagation delay and array responsenestimation methods are also proposed in this paper
