Blind Doppler Rate Estimation for PSK Signal

Xin Cai, Xiang Wang, Zhi-Tao Huang, Feng-Hua Wang
We propose a novel blind Doppler rate estimator for phase shift keying (PSK) transmissions. The issue may arise in mobile radio links when the received signal experiences non-negligible time-varying Doppler distortion, as in low earth-orbit satellite systems and terrestrial mobile cellular radio systems....
