High-resolution estimation for time-variant MIMO channel soundings

Abstract:

A wideband vector channel sounder with 16 parallel RF chains is proposed for 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 centred at 2.45 GHz. Experimental results show errors inferior to I ns in the time domain and of few degrees in the angular domain. Accurate results are found in static as well as in time-variant scenarios.
