Abstract: | For MSK modulation signals, two SNR estimation methods of second and fourth Moment and Synchronous Header Relation are researched, and their features are obtained according to simulation of the estimation mean square error performance and comparison with Cramer-Rao Bound. Finally, the application range of each method is proposed. |
