Abstract

This paper introduces a line-of-sight (LOS) and non-LOS (NLOS) separation technique based on the statistics of the phase difference of two received signals. The phase difference is achieved via a co-installed synchronized two-receiver system. The variance of the phase difference is used to separate LOS and NLOS. The probability-density-function (PDF) of the received signal phase generated by NLOS component is theoretically derived. The variance of the phase difference is calculated using the derived PDF numerically and verified via simulations. The LOS and NLOS separation performance versus signal power ratio of LOS to NLOS is evaluated via simulations.
