GEDOMIS® (GEneric hardware DemOnstrator for Multiple Input Multiple Output (MIMO) Systems) is an experimental platform that comprises a complete set of high performance baseband prototyping boards (FPGA and DSP-based), signal generation equipment, high-end RF front-ends, signal analysis instruments, specialized software tools and APIs. A key instrument of the testbed is the EB Propsim C8 channel emulator, which can be configured to provide realistic mobility scenarios of both certified and user-designed channel models. The Propsim C8 operates in real-time and facilitates the verification and testing of system designs prior to field-trials. Hence, GEDOMIS® offers a laboratory environment that enables the prototyping of next generation broadband wireless communication systems, which feature bit-intensive OFDM PHY-layer techniques combined with multi-antenna schemes.
A real-time baseband implementation of a MIMO-OFDM mobile WiMAX transmitter and receiver, namely BeMImoMAX, (DL, TDD, single user, point-to-point) is the first CTTC's high-performance HDL IP to reach the market. A real-time PHY-layer prototype based on LTE and running on FPGA devices is currently under development. The latter, together with other HDL IPs planned to be released in 2012, will enhance the portfolio of CTTC.
BeMImoMAX was validated using the FPGA boards of GEDOMIS® (i.e., VHS-DAC, VHS-ADC and SMQUAD-V4 from Nutaq, whereas the remaining hardware setup of GEDOMIS® provided a realistic environment to test diverse emulated mobility conditions. Note that BeMImoMAX is currently ported in a new baseband platform of Nutaq based on the Perseus 601X and the Radio 420X boards. The steps of the design and implementation flow are summarised in the following lines:
The PHY-layer of BeMImoMAX includes a limited subset of the flexible OFDM configuration defined in the IEEE 802.16e-2005 standard specifications (i.e., the current version of the baseband prototype has fixed bandwidth, modulation scheme and FFT size).
More details of the implementation and validation will be added soon.
BeMImoMAX showcases a high performance VHDL implementation of the IEEE 802.16e-2005 standard PHY-layer. An outline of its main features is given in this section.
As of 27th of February 2012 BeMImoMAX is available to purchase from:

We are proud to announce the public release of BeMImoMAX during the Mobile World Congress 2012. Please visit CTTC's booth (Hall 3.0 Courtyard - CY03) or Lyrtech RD (Nutaq) booth (Hall 2, 2A101) for more information.
GEDOMIS® will have its first presence at the Mobile World Congress (MWC). A remote demo connection with the laboratory will be offered to the visitors of the CTTC stand at the MWC. Come to visit us at CTTC's booth (Hall 3.0 Courtyard - CY03) to get more infomation on our R&D activities.
Oriol Font together with Nikolaos Bartzoudis and Miquel Payaró had their inter-consortium (BeFemto FP7 ICT, call 4 ongoing project) proposal approved for a six-month project that will demonstrate interference mitigation techniques in a test scenario that includes (i) one LTE-based Macro BS (eNodeB) and a user and (ii) one femto BS (HeNodeB) and another femto user. FPGA-based prototypes will be developed for the above BSs and UEs.
Oriol Font presented a paper during the EUSIPCO 2011 conference entitled "Prototyping Processing-Demanding Physical Layer Systems Featuring Single or Multi-antenna Schemes".
Antonio Pascual has worked in the Publication section of the conference. Nikolaos Bartzoudis was member of the local committee.
Nikolaos Bartzoudis presented a paper entitled "A Real-Time FPGA-based mobile WiMAX transceiver supporting multi-antenna configurations" on the 5th Argentine Conference on Micro-Nanoelectronics, Technology, and Applications. Technology transfer liaising during the industry day of the conference.
Nikolaos Bartzoudis gave a tutorial on design & prototyping techniques of compute-intensive baseband processing systems at the National University of La Plata (Argentina). A follow up invited talk explored potential collaboration possibilities.
The funded research project is expected to start in the beginning of 2012 and its duration will be 3 years. The focus of this collaborative project is on energy awareness and harvesting issues in modern communication terminals and it will be developed in collaboration with the University Carlos III of Madrid. The project will be funded by the Spanish Ministry of Science and Innovation (call CICYT 2011). Toni Pascual, Miquel Payaró and Nikolaos Bartzoudis have worked for the preparation of the proposal.

After designing the Matlab model of the PHY-layer of a MIMO mobile WiMAX transmitter (2x2 MIMO), the corresponding real-time VHDL implementation has been validated and tested in the GEDOMIS® testbed FPGA boards. This will allows us to substitute the currently used emulation of the MIMO mobile WiMAX transmitter (i.e. comprised by two vector signal generators that playback in real-time a Matlab-generated WiMAX signal) with our FPGA-based custom VHDL real-time implementation.
