Abstract

A wideband vector channel sounder with sixteen parallel RF chains is proposed for joint parameter estimation in an indoor channel. Low-cost and high-resolution are obtained by using a chirp probe signal, five-port receivers and the MUSIC algorithm. The system covers up to 500 MHz around 2.45 GHz. Experimental results show errors inferior to 1ns in the time domain and of few degrees in the angular domain (Direction of Departure and Direction of Arrival). Measurements in a corridor are presented.
