Abstract :
A novel timing tracking algorithm suited for multi-carrier DS-CDMA signals by introducing vector rotation and samples selecting is proposed and studied. Numerical results shows that the new scheme has a remarkable hardware simplicity advantages but no performance degradation when compared to the conventional non-coherent delayed-lock loop (DLL).
