Over-the-air demonstration of spatial multiplexing at high data rates using real-time base-band processing
Fraunhofer Institute for Telecommunications, Heinrich-Hertz Institut, Einsteinufer 37, D-10587 Berlin, Germany
Abstract. Over-the-air transmission experiments with a realtime MIMO test-bed are reported. We describe in principle a hardware architecture for spatial multiplexing at high data rates, discuss in detail the implementation on a hybrid FPGA/DSP platform and show measured bit error rates from indoor transmission experiments. Per-antenna rate control and joint transmission are enabled as well using an ideal feed-back link. A functional test of these new techniques is described while detailed transmission experiments are still ongoing.
