Abstract :
A new system based on five-port reflectometers, which measures simultaneously direction of arrival (DoA) in azimuth plane and propagation time of arrival (ToA) of multi-path signals for indoor communication applications is presented in this paper. The receiver operating at 2.4 GHz consists of seven five-ports and a uniform linear array (ULA) of seven quasi-Yagi antennas. The data processing method is also presented. Estimation procedure for joint DoA and ToA is based on the multiple signal classification (MUSIC) algorithm associated with spatial smoothing pre-processing (SSP). The simulation and experimental results show that the DoA and the ToA of multi-path signals are well estimated
