Abstract
This paper presents a flexible demonstrator platform for cooperative joint transmission and detection in next generation wireless networks, especially cellular networks like 3GPP LTE+. The platform is shown capable of handling computational load as well as network load of jointly processing three maximum bandwidth LTE sectors with four antennas each. The platform uses a Workstation mainboard as PCI Express backplane. Joint signal processing is done on a Cell processor, protocol handling on an IXP2350 network processor. For baseband sample exchange a 10GBit/s optical network interface card is used. First results show the Cell processor capable of computing the 12x12 modified LTE MIMO-OFDM processing concurrently for precoding (downlink) and postprocessing (uplink) with a MIMO matrix update interval of 1ms (high mobility).
