Multi-path delay measurement based on five-port discriminator

A new system based on five port discriminator which measures multi-path delays through the use of the frequency sounding technique is presented. The multi-path delays are estimated by using not only Inverse Fast Fourier Transform OFFT) but also the high resolution method Multiple Signal Classification (MUSIC) when it is associated with Spatial Smoothing (SS) method. In addition, we also show that it is capable of estimating the time delay and direction of arrival (DoA) simultaneously using five-port technique.
