PSD-based Doppler Estimation for TDD Systems
We present a new Doppler estimation for time division duplex (TDD) systems using power spectral density (PSD) based method. First, a detailed analysis of the effect of TDD frame structure is proposed. Based on the results of analysis, we proposed a method of getting the best detection of Doppler spread by adaptive thresholding and a method of eliminating the partial aliasing of PSD by linear interpolation. Then we compared with the existing methods, the new algorithm is accurate and robust to noise. It is also shown that the PSD-based algorithm has good performance for wide range of Doppler spread and suitable for next generation wireless communication systems, such as TDLTE.
