Channel estimation method and channel estimator for an electromagnetic wave multi-path characteristics between the transmitter and the receiver using a chirp signal

摘要

And outputting a sum of individual frequency components resulting from difference in distance of multiple paths for each of the chirp signal portion, - a down-chirp signal portion - [SOLUTION] (a) chirp - up of the modulated signal - deviation and down chirp signal portion - - up of the sum of (b) the individual frequency components and calculating the deviation frequency output over each other the output of each of the chirp signal portion, of the individual frequency components using the (c) deviation frequency output discontinuities by performing the frequency correction output a correction for discontinuity of the modulation signal between the steps of: - generating a frequency compensation output by performing the correction of the frequency deviation of the sum, the chirp (d) generation - shift and generating a discontinuous compensated outputs, and is broken down to the individual multipath signals discontinuity compensation output by applying (e) a frequency analysis method, and time delay caused by decay component (f) multi-path channel channel estimation method and a step of extracting is provided a component.
