Abstract :
This paper investigates non-data-aided (NDA) SNR estimation for QAM transmission over additive white Gaussian noise channels. It proposes a novel class of moment-based SNR estimators. This class is found to be a generalization of the well-known moment-based M2M4 SNR estimation method for PSK modulation. The performance of the proposed estimators is evaluated for M-PSK and rectangular 16-QAM modulation.
