Joint space-time estimation for DS-CDMA systemin fast fading multipath channel
Zhenghui Gu, Endra Gunawan · Electronics Letters · 2001
A space-time array manifold model is developed for an asynchronous DS-CDMA system over a fast fading channel in a multipath environment. The MUSIC algorithm is applied to the model to extract both the path delays and directions of arrival from the uplink signals. It is shown that this method can resolve the different paths while the conventional approach fails.
