GEDOMIS® (GEneric hardware DemOnstrator for Multiple Input Multiple Output (MIMO) Systems) is an experimental platform that comprises a complete set of baseband prototyping boards, signal generation equipment, high-end RF front-ends, real-time channel emulation, signal analysis instruments and specialized software tools. This results in 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.

GEDOMIS® has served as a flexible experimental research platform for the prototyping and validation of the following high performance wireless communication systems as part of competitive funding projects:

• WLAN receiver enabling four antenna MIMO reception (non real-time) built on a TI DSP.
• Project name: MARQUIS (Medea+ program, Ref.: A111).
• Funded by the Spanish Ministry of Industry, Commerce & Tourism.
• Duration: 01/2003 – 06/2005.
• Real-time FPGA-based mobile WiMAX receiver enabling two antenna MIMO reception.
• Project name: MIMOWA (Medea+ program, Ref.: 2A103).
• Funded by the Spanish Ministry of Industry, Commerce & Tourism.
• Duration: 01/2007 – 06/2009.

• Evaluation of new indoor and outdoor channel models using the experimental setup of GEDOMIS® and cognitive radio paradigms.
• Project name: NEWCOM# (FP7).
• Funded by the EC (Contract number 318306).
• Duration: 01/11/2012 – 31/10/2015.
• Implementation and experimental validation of a broadband Fast-Convolutional Filter-Bank Multi-Carrier transmitter (FC-FBMC), with a single and two-antenna configuration, able to coexist in the same band with PMR units by employing cognitive radio techniques.
• Project name: EMPhAtiC (FP7).
• Funded by the EC (Contract Number 318362).
• Duration: 01/09/2012 – 1/03/2015.

GEDOMIS® is currently being used to implement and prototype algorithms and technologies for 5G communication systems.

• Flexible partitioning and reconfiguration of LTE hardware-accelerated (HWA) and software (SW) communication stack functions which are distributed across different processing domains of the radio access network (RAN) in order to optimize different KPIs. Use, extend and modify the existing HWA FPGA-based LTE L1 (developed in the BeFEMTO project) and interface it with the LENA simulator (L2 and above) at eNB and UE level; LENA runs on CTTC’s EXTREME® The network flexibility is achieved by switching from a given network configuration (NETCFG) to another one featuring a different partitioning of its underlying SW and HWA communication stack functions and/or by modifying specific wireless communication parameters (WCP) or a functional set of L1 blocks.
• Project name: Flex5Gware (H2020).
• Funded by the EC (Contract Number 671563).
• Duration 01/07/2015 – 30/06/2017.
• Coexistence of broadband 5G waveform with narrowband trasmissions or 4G LTE in the same band under licensed fragmented spectrum scenarios.
• Project name: AEThER.
• Funded by the Spanish ministry of Economy and Competitiveness (MINECO) under the funding scheme “Proyectos de I+D+I Retos investigación 2014”, Reference TEC2014-58341-C4-4-R.
• Duration 01/01/2015 – 31/12/2017.
