Novel PN code timing tracking loop for DS/CDMA systems

In this paper a novel non-coherent all-digital timing tracking scheme is described and analyzed for chip timing synchronization in direct sequence spread spectrum systems. Results of the theoretical analysis and computer simulations show that the scheme improves tracking performance as compared with the traditional delay-locked loop (DLL) in an AWGN environment. Also, the new scheme enhances the hardware simplification with respect to other traditional non-coherent schemes.EI04675-6792
