An Alternative Carrier Phase Independent Timing Recovery Methods for VSB Receivers

In this paper, we propose an alternative carrier phase independent timing recovery method for VSB receivers. The Gardner algorithm may not estimate the timing offset in VSB systems when the residual carrier phase offset is contained in the signal. We use the conjugate multiplication of received signals to cancel the carrier phase offset. Then, the Gardner algorithm [1] is employed to extract the spectral line. The proposed method generates a consistent timing error, even in the presence of the carrier phase offset.
