【简　介】:Abstract: This paper is concerned with the active
identification of a multipath propagation channel. The
correlation method and a frequency domain de-
convolution are used to convert the TOA (time of
arrival) estimation problem to an estimation of
frequency. In the case of stationary Gaussian noise
(after the de-convolution), a new approach was
proposed by the use of the higher order cumulants of
the measurements data. The noise was suppressed and
the TOA estimation can be obtained correctly. Finally
simulation examples are presented to illustrate the
effectiveness of this approach.
