Abstract :
In the context of Software Defined Radio (SDR), parameterization technique is an interesting approach for the design of multi-standard terminals. It limits the size of the software to a small set of parameters thereby decreasing the radio reconfiguration time. In the proposed research, we refine the Common Operator (CO) technique, which defines a multi standard terminal, based on a limited set of Common Operators. This method enhances the reconfigurability and the scalability of the design but leads to a complex management of data dependencies and scheduling of each operator for its correct execution in the terminal. In this paper, we present a new organization in bank (COB) not only to mitigate the scheduling issue but also to maintain the flexibility and the optimization inhere in the technique. The COB benefits from the property of the CO though limiting the main part of the scheduling. The COB creates a scalable design, limits the scheduling and reduces the number of operators. Applied in the case of LFSR targets to a tri-standard terminal, it lowers the hardware complexity by up to 40%.
