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 is employed to extract the spectral...
In relating the use of consumer-grade equipment, Carrier Synchronization is a difficult task for DVB-S2 receivers, which have to operate with a large initial Carrier Frequency Offset (CFO) yet needing to achieve relatively high estimation precisions. For these reasons, conventional Carrier Frequency Recovery schemes for DVB-S2 systems need significant hardware complexity. In contrast, this paper proposes...
