For the sake of the potential ability of overcoming interference in TD-SCDMA(time division-synchronous code division multiple access) systems, pilot signal is adopted, but the presented TD-SCDMA protocol has not considered the Rake technique for their mobile terminals. This paper developed a RAKE receiver algorithm and an implementation circuit, which make use of the pilot signal in the burst structure of the TD-SCDMA base station to estimate main channel parameter (channel delays) in the downlink of TD-SCDMA wireless network. The algorithm can reduce multipath interference for the mobile units in multiusers’ case. Theoretic performance analysis presented in the paper and computer simulations confirm that the proposed RAKE receiver algorithm achieved a better BER performance under multipath fading propagation and multiusers conditions.
Keywords:wireless communication， TD-SCDMA RAKE receiver schemes, channel parameters estimation
