摘      要：正This paper is concerned with the active identification of a multipath propagation *** correlation method and a frequency domain deconvolution are used to convert the TOA（time of arrival） estimation problem to an estimation of *** 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 *** noise was suppressed and the TOA estimation can be obtained *** simulation examples are presented to illustrate the effectiveness of this approach.
