Bing Wang · Electronic Design Engineering · 2013
This paper researches the SNR estimation algorithms that based on the data-aided maximum likelihood SNR estimator,based on the order and high order moments SNR estimation method of QPSK modulation signals.The simulation result compares the algorithms and shows the influence of iteration numbers and the data length parameters on the performance of the algorithm.Finally,the paper gives the applicable range according to the features of each estimator.
