prior estimate
1.An SNR estimation algorithm was d eveloped based on eigenvalue decomposition of the correlation matrix of the rece ived signals and the principle of minimum description length (MDL) in informatio n theory. The algorithm can estimate the SNR of digital modulation signals commo nly used in additional white Gaussian noise (AWGN) channels and multipath channe ls without prior information of the modulation type, baud rate or carrier freque ncy of the signals.
