Abstract	Abstract—Future wireless systems are evolving towards a broadband and open architecture for efficient multi-service oper-ation. This has a great impact on the terminal and infrastructure component design methodology for supporting multiple radio schemes. Cooperation in wireless networks, requiring cognitive radio implementations, will facilitate a new dimension in the evolution of multimedia communications. The growing price pressure requires ever increasing levels of integration efficiency, flexibility and future proofness at the same time, setting out in the digital baseband domain. In this manuscript, the authors will illustrate a platform based prototyping process, which combines the advantages of the flexibility of a digital signal processor with the efficient parallelization capabilities of a field-programmable gate array. The primary purpose of this platform is to allow a real-time capable implementation of cognitive radio systems. It allows the integration of the entire communication chain from the antenna to the decoded bit stream. Since the increasing computational complexity complicates the dimensioning of such platforms, scalability is a crucial design constraint for the presented concept.
