Abstract
- Gardner's timing method for BPSK or QPSK is actually one of the timing methods using the Nyquist sidebands. However, it requires at least two samples per symbol; and it is more suitable for two-level modulations. This paper presents another timing synchronization method that is suitable for ATSC DTV receivers, in which 8-VSB modulation is used. The correlation of both arms of the VSB signal is exploited. The S-curve of the proposed method is derived. Derivation shows the proposed method is also using the Nyquist sidebands. It can estimate the timing error even at symbol-rate. Simulations show the proposed method has good performance even in multi-path conditions. [ABSTRACT FROM AUTHOR]
