A RAKE receiver for TD-SCDMA mobile terminals

The paper develops a RAKE receiver algorithm which makes use of a pilot signal broadcast by the TD-SCDMA (time division-synchronous code division multiple access) base station to obtain channel parameter estimates in the downlink of a TD-SCDMA wireless network. The algorithm can reduce multipath interference for mobile units. The presented performance analysis and computer simulations confirm that the proposed RAKE receiver algorithm achieves a better performance under typical multipath fading propagation conditions.
