Abstract :The aim of this study is to reduce the effect of in-band interference in delay profiles estimated from frequency modulated continuous wave sounder channel data. In-band interference distorts the detector output signal, and increases the noise floor of delay profiles, which obscures weak multipath components. This study shows that the Eigenvector method can be used to improve estimates of delay profiles from FMCW channel data corrupted with in-band interference.
