Graphical Approach for Multi-standards Radio Design Formalization and Global Optimization

Abstract : This article describes a graphical approach for multistandards SDR design formalization. An SDR consists of software components whose behavior can be changed by reconfiguration procedure. In a common operator design this change requires only an adjustment of certain parameters. The optimal way of realizing a multi-standards terminal is to identify the common functions and operators between standards. Various common operators have been identified that can be used to obtain an optimal solution that balances between cost and efficiency. The need for optimization in multi-standards software defined radio equipments due to increasing complexity is of vital importance. In order to optimize the choice of these operators we first make an oriented graph that shows the interrelationship between various components of the system. Then, an architectural exploration extracts the common operators of a given multi-standard system. Moreover this article explains how we can obtain a global minimum by merging different common operators. This is elaborated with the help of a simplified tristandards example that shows the advantages we can have by merging dual mode fast Fourier transform (DMFFT) operator and frequency response masking filter-bank (FRMFB) operator.
