Identification of LOS in Time-Varying, Frequency Selective Radio Channels

Abstract

A method is proposed to identify the existence of line-of-sight (LOS) for time-varying, frequency selective radio channels. The proposed method considers the second-order statistical characteristics of underlying process in the channel taps. Identification is established by comparing the autocorrelation coefficients of the first tap with those of any other tap when the other tap reaches its coherence time. Numerical results and related discussions are presented considering several practical scenarios.
