Comparative Performance analysis of Symbol Timing Recovery Techniques for DVB-S2 Receivers

The 13th Ka and Broadband Communications Conference, Turin, Italy, September 2007.

Abstract: The need for reliable broadband satellite communication services has led to the development of the second generation DVB spec, DVB-S2. This paper considers the performance of a feedback Symbol Timing Recovery technique, which is based on the Non-Data-Aided (NDA) Gardner Timing Error Detector (TED), in an all-digital DVB-S2 IF receiver architecture. The Symbol Timing Recovery performance is measured in terms of lock-in time and estimation accuracy, with the contribution of simulation results over all different modulation schemes used by the DVB-S2 standard (QPSK, 8PSK, 16APSK and 32 APSK) and under noise sources such as non-linearities, additive white Gaussian noise (AWGN) and significant residual carrier frequency offset.
