Comparison of decision-directed and pilot-aided algorithms for complex channel tap estimation in a downlink WCDMA system
A. Zhuang, Elena Simona Lohan, Markku Renfors · 2002
We evaluate three decision-directed algorithms for complex multipath channel tap estimation in the downlink wideband CDMA (WCDMA) system. These algorithms are tested with indoor and vehicular channel models at different mobile velocities and their performance is compared with ideal channel estimation, as well as with estimation based on linear interpolation.
