A real-time pre-MIMO-LTE software radio testbed

The contribution describes the implementation of a MIMO (Multiple Input - Multiple Output) OFDM (Orthogonal Frequency Division Multiplex) online demonstrator with certain parameters for the 3rd Generation Partnership Project (3GPP) Long-Term-Evolution (LTE) system, by employing our scalable multi-standard Software Defined Radio (SDR) Testbed [1][2], which is built up with Sundance modular hardware components [3]. In comparison to prior MIMO test-bed installations, the entire digital signal processing is achieved in real-time using Texas Instruments DSPs and Xilinx FPGAs. It indicates that our MIMO Testbed structure can accelerate the development and evaluation of the techniques for the next generation wireless communication systems.
