N2 - A Modified M&M frequency estimation algorithm for DVB-S2 system is proposed in this paper. This estimator provides a larger estimation range compared to the well known Fitz and L&R methods and achieves CRB in the whole SNR operation range of DVB-S2, with a little increase in computational complexity. The enlarged estimation range will reduce the acquisition time of the coarse frequency synchronizer in a two-step carrier frequency recovery scheme. Minimum accumulation lengths to achieve a certain RMS frequency estimation error for the L&R and Modified M&M estimator at different SNR are presented. A variable accumulation length scheme based on SNR estimation or coding/modulation scheme employed in system is proposed to minimize the acquisition time in the One frequency recovery.
