OFDM ICI Method and Apparatus for removing Inter subCarrier Interference effect in Orthogonal Frequency Multiplexing radar systems

摘要

[0001] The present invention relates to a radar system, and more particularly to a radar system in which an Inter subCarrier Interference (ICI) generated when extracting Doppler information (or speed information) of a target object in an OFDM (Orthogonal Frequency Division Multiplexing) And more particularly to a method and an apparatus for removing a substrate. According to the present invention, the ICI (Inter subCarrier Interference) generated at the time of signal processing can be eliminated, and the accurate velocity information of the target can be estimated due to the reduction of the ICI.
