摘要
A wireless communications receiver includes a receiving unit configured to receive a radio transmission having Doppler distortion and channel noise. Also included is an estimating unit coupled to the receiving unit and configured to determine a noise-abated maximum Doppler frequency estimate for the Doppler distortion. Additionally, the estimating unit is further configured to determine a signal-to-noise ratio (SNR) estimate based on the noise-abated maximum Doppler frequency estimate. In another aspect, a method of operating a wireless communications receiver is provided.
