An average SNR (signal-to-noise ratio) estimation method, based on channel power spectrum density (PSD) analysis, is proposed here. It can be implemented by FFT to reduce operations effectively. Also, we analyze the bias of Doppler shift estimation and recommend an improved estimation method based on SNR estimation. A high estimation accuracy in wide ranges of velocity and SNR is observed from simulation results.
