A Joint Algorithm of SNR Estimation for Expanding Estimation Range
Zhipeng Wang, Yubai Li · 2021 IEEE 21st International Conference on Communication Technology (ICCT) · 2021
In the field of SNR estimation, the existing cumulant algorithms can not estimate SNR accurately in both high and low SNR. In this study, the author compared the effective range of several non-data-aided(NDA) SNR estimators, proposed a joint SNR estimation method for quadrature-phase-shift keying(QPSK) modulated signal to expand the estimation range effectively.
