Abstract
This paper proposes a non-data-aided (NDA) SNR estimation algorithm for QAM signals in additive Gauss white noise channel and on the condition of the equivalent priori probabilities of every constellation signals by using second statistics. The detail analysis and computer simulation for 128QAM signals have been done. It has been proved that the SNR range interested in practice can be estimated In this algorithm.
