Abstract

A hardware simulator can simulate a desired radio channel, making it possible to test "on table" various mobile radio systems. This paper presents the new architecture of the digital block of an Outdoor-to-Indoor MIMO hardware simulator. Measurements campaign carried out at 3.5 GHz has been conducted to obtain the impulse responses using a time channel sounder. The measurements are processed with a high resolution algorithm extracting the dominant paths. The new architecture is implemented on a Xilinx Virtex-IV FPGA. The accuracy, the occupation on the FPGA and the latency of this architecture are analyzed.
