Adaptive beamforming algorithms continue to be a research hotspot of smart *** adaptive beamforming algorithms,non-blind adaptive algorithms attract most researchers’ interests because they have better feasibility,stability performance and they are not affected by the accuracy of DOA *** performance of non- blind adaptive algorithms used in TD- SCDMA communication system has not been studied and simulated in- depth *** paper tries to simulate and compare three typical non-blind adaptive algorithms including Least Mean Square algorithm(LMS),Recursive Least Squares algorithm(RLS),the Sample Covariance Matrix Inversion algorithm(SMI) for TD- SCDMA *** simulation results show that all three algorithms can mitigate interferences,save power and improve the quality of *** simulation also indicates that better performances and applicability are obtained when the weights are estimated using the RLS algorithm than the LMS and SMI algorithms.
