In this paper a new blind estimation algorithm is proposed which uses Singular value decomposition of signal self-correlation matrix to estimate Signal-Noise-Ratio (SNR) of non-constant envelope signal over AWGN channel.The theoretic analysis is also given.Computer simulation results show that the performance of this algorithm is robust and the estimation error is less than 0.5dB when the actual SNR ranges from 1 to 20dB for MPSK and MQAM signals.
