- 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. The algorithm first removes the phase modulation without training sequence and then utilizes spectral characteristics of the transformed signal, which ensures its simplicity of implementation. Iterative section is introduced to help enhancing the adaptability and accuracy. The proposed method is almost insensitive to Doppler shift and performs well over a wide range of Doppler rates. Comparisons with existing methods are discussed.
