Scalable Multi-tasking Baseband for Mobile Communications

The MULTI-BASE consortium will demonstrate new handset baseband architectures that enable end-to-end interconnections of humans and devices drawing on the three areas of multi-tasking radio, scalable reconfigurable multiprocessor technology and algorithm/architecture co-design.




To meet the new challenges such as reconfigurability and flexibility but with low power consumption and low silicon area, completely new chip architectures and circuits for the digital baseband processor are required. The traditional mobile phone is quickly changing from being a voice communication device with rudimentary messaging capabilities, communicating over a single network type, to becoming a portable multimedia, multi-network hub. A natural evolution is that a mobile terminal will need to handle simultaneous wireless streams. In order to strengthen Europe’s leading position in high-speed, end-to- end, mobile network systems technology, the MULTIBASE consortium has identified three main areas where research will have a major impact on the advancement of state-of-the-art technology and the emergence of a sound competitive and innovative environment for the European communications and services industry:
  • Multi-tasking radio (concurrent execution of multiple standards, multiple connections on a shared platform)
  • Scalable programmable/reconfigurable Multi Processor Technology (MPSOC Frameworks) and
  • Algorithm/Architecture co-design for maximum energy efficiency.
The MULTI-BASE project objectives target the elimination of key technical and commercial barriers to ubiquitous broadband access by enabling efficient and sustainable disposition of operation and production factors as spectrum, power engineering cost and silicon process technology.


  • Focus on the requirements and feasibility of two main concurrent communication modes (multi-tasking radio) to create a European leading-edge solution for multistandard communication
  • Identify an architecture enabling a reconfigurable transceiver baseband processing chain with shared building blocks for simultaneous multi-standard communication
  • Demonstrate the design for a proof of concept of a reconfigurable digital baseband platform capable of
  • executing emerging air interfaces such as 3GPP LTE and IEEE 802.11g/n as well as
  • executing at least two air interfaces in parallel and satisfying the real time constraints of both
  • Implement the key building blocks to prove the breakthroughs in energy-efficiency and implementation cost– proof of concept in silicon
  • Overcome barriers to the widespread commercial use of reconfigurable digital baseband implementations in mobile terminals.

Project Results and Innovation:

Currently most system-design of digital radio baseband is done isolated for every standard. All commercially available multi-mode baseband solutions employ different single standard baseband without hardware reuse. So far no solution is modular and configurable enough to accommodate different applications. The solutions that are capable of higher complexity processing are not yet capable of multiple standard concurrent executions. In current technology node, the state-of-the-art programmable baseband solution is not capable of supporting the emerging new standards with for instance multi-antenna features with acceptable power budget.


The MULTI-BASE consortium consists of two leading European mobile communication chip and platform developers together with three universities and a large applied research insitute in area of telecommunications.

The consortium guarantees the fundamental innovative character of the reseach and the applicability in further industrial applications, initiating a major technical leadership in the design and implementation of digital baseband processors for mobile platforms. The knowledge is streching from basic research to the design and marketing of products, including the production, evaluation and standardisation of all parts targeted by the project as well as intimate knowledge of the end-user market.
