A reduced-complexity all-digital timing tracking scheme suited for multi-carrier CDMA signals is proposed and studied. Based on samples selecting and vector rotation of correlation output vector at only on time channel, timing error detection statistics are approximately acquired and timing adjustment are carried out. Theoretical and numerical results show that the new scheme has an improved performance and remarkable complexity simplicity as compared with the classical digital delay-locked loop.
