Abstract :
This paper describes the development of the multi-input multi-output (MIMO) channel sounder which can jointly estimate the direction of departure (DOD), the direction of arrival (DOA) and the delay time of arrival (DTOA), for the advanced modeling of wireless channels. The algorithm and the hardware architecture are described, as well as the experimental results using the prototype.
