Haifeng Xiao, Yun Q. Shi, Wei Su, JOHN A. KOSINSKI · 2010
This paper investigates the non-data-aided SNR estimation techniques for analog modulation signals. Two existing algorithms, M2M4and ED-based estimators, are modified and applied to SNR estimation for signals with analog modulation. This paper also proposes a simple but practical Spectrum-based SNR estimator for analog modulation. The performances of the three SNR estimators are compared and analyzed.
