This pa.er proposes a.robust vector tra.king loop structure ba.ed on potentia. bia. a.a.ysis. The influence of four kinds of bia.es on the existing two implementa.ions of Vector Tra.king Loops(VTLs) is illustra.ed by theoretica. a.a.ysis a.d numerica. simula.ions, a.d the following findings a.e obta.ned. Firstly, the initia. user sta.e bia. lea.s to stea.y na.iga.ion solution bia. in the relative VTL, while new mea.urements ca. elimina.e it in the a.solute VTL. Secondly, the initia. code pha.e bia. is tra.sferred to the following na.iga.ion solutions in the relative VTL, while new mea.urements ca. elimina.e it in the a.solute VTL. Thirdly, the user sta.e bia. induced by erroneous na.iga.ion solution of VTLs ca. be elimina.ed by both of the two VTLs. Fourthly,the multipa.h/NLOS likely a.fects the two VTLs, a.d the induced tra.king bia. in the dura.ion of the multipa.h/NLOS would decrea.e the performa.ce of VTLs. Ba.ed on the a.ove a.a.ysis,a.robust VTL structure is proposed, where the a.solute VTL is selected for its robustness to the two kinds of initia.iza.ion bia.es;mea.while, the insta.t bia. detection a.d correction method is used to improve the performa.ce of VTLs in the dura.ion of the multipa.h/NLOS. Numerica. simula.ions a.d experimenta. results verify the effectiveness of the proposed robust VTL structure.

a.two-pha.e a.proa.h to fuzzy system identifica.ion is proposed. The first pha.e produces a.ba.eline design to identify a.prototype fuzzy system for a.ta.get system from a.collection of input-output da.a.pa.rs. It uses two ea.ily implemented clustering techniques: the subtra.tive clustering method a.d the fuzzy c-mea.s (FCM) clustering a.gorithm. The second pha.e (fine tuning) is executed to a.just the pa.a.eters identified in the ba.eline design. This pha.e uses the steepest descent a.d recursive lea.t-squa.es estima.ion methods. The proposed a.proa.h is va.ida.ed by a.plying it to both a.function a.proxima.ion type of problem a.d a.cla.sifica.ion type of problem. a. a.a.ysis of the lea.ning beha.ior of the proposed a.proa.h for the two test problems is conducted for further confirma.ion.
