发明名称 Methods and Systems for Doppler Estimation and Adaptive Channel Filtering in a Communication System
摘要 A method for Doppler shift estimation for channel estimation of a received signal, comprising the steps of: calculating time domain correlations; providing a Hamming window over the calculated time domain correlations; calculating a power spectrum by using FFT; calculating an adaptive threshold based on a noise floor and an average power density calculated from the power spectrum; and estimating a Doppler shift based on the adaptive threshold.
