— In this paper, we present real-time broadband multiuser multi-antenna measurements in typical indoor and outdoor scenarios. For the first time, essential frequency-selective functions of a new medium access control (MAC) layer, namely fair resource assignment to multiple users, spatial mode selection and adaptive modulation, have been implemented in(More)
In this paper we focus on channel adaptive transmission in the multiuser OFDM Uplink where the base station uses multiple antennas. The additional degree of freedom in space requires extra signal processing effort which becomes challenging especially for a high data rate implementation in real-time. Our MIMO-OFDM experimental system which is capable to(More)
In this paper we report on the system design and a real-time implementation of a MIMO-OFDM radio transmission system close to physical layer parameters as discussed in standardization for 3GPP-Long-Term-Evolution. We describe the implementation concept and first results on over-the-air transmission with a single user setup occupying 20 MHz bandwidth and(More)
