  • Abstract
    Two simple phase-based correlation methods, i.e. phase correlation and line fit phase correlation, using non-data-bearing (NDB) orthogonal frequency division multiplexing (OFDM) transmission, are proposed for line-of-sight (LOS) time-based range estimation (TBRE) in a frequency selective multipath channel based on the characteristics of the probing signal. Simulation results show that both proposed methods for NDB OFDM based TBRE have much more distinct LOS peaks than conventional correlation, leading to a better ranging accuracy.
