FIR-RAKE receiver for TD-SCDMA mobile terminals

This paper proposes a FIR-RAKE receiver algorithm that 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 TD-SCDMA wireless network. The algorithm can reduce multipath interference for the mobile units and with lower complexity of FIR implementation, where only one marching filter has been adopted. Performance analysis presented in the paper and computer simulations confirm that the proposed FIR-RAKE receiver algorithm achieves a better performance under typical multipath fading propagation conditions
