Yin De-qiang · Ceshi jishu xuebao · 2012
This paper applies the time-frequency method for SNR estimation and uses the Matlab to perform simulation.The results indicate that the frequency choice number,sample frequency and time length have an influence on the SNR estimation.Under proper parameters,the average error of SNR estimation can be lower than 0.15dB.
