Novel data-aided SNR estimation algorithm for QPSK signal in AWGN channel

Novel data-aided SNR estimation algorithm for QPSK signal in AWGN channel was presented. The analytical and simulated results show that the new SNR estimator performs better than ML-DA estimators, especially in the condition of low SNR, it is more precise and more reliable, and is not sensitive to p...
