Joint Doppler Shift and Channel Estimation for UAV mmWave System with Massive ULA
文献摘要：
A joint Doppler shift and channel estima-tion method for the millimeter-wave communication system of an unmanned aerial vehicle(UAV)equipped with a large-scale uniform linear antenna(ULA)array has been proposed.Since Doppler shift induces in-tercarrier interference,the parameters of the channel paths have been decomposed into the Doppler shift and the channel information.In order to obtain the Doppler shift,a new estimation algorithm based on a combination of discrete Fourier transform and phase rotation has been proposed,which can determine the appropriate number of antennas.In addition to es-timating the channel information,a low-complexity joint Doppler shift and channel estimation method has been designed that can quickly obtain accurate esti-mates.Furthermore,the achievable sum rate,the the-oretical bounds of the mean squared errors,and the Cramér-Rao lower bounds of the estimation method have been derived.The analysis and simulation results prove that the performance of the proposed approach is close to the theoretical inference.
