A Workbench for Analytical and Simulation Based Design Space Exploration of Software Defined Radios

摘要

This paper presents a workbench addressing the issue of early design space exploration for Software Defined Radios (SDRs). Key contribution is a pre-simulation mathematical analysis based on Synchronous Data Flow (SDF) graphs, which supports system architects in their soft- and hardware design decisions at early design stages. The analysis is integrated into an Electronic System Level (ESL) based simulation framework allowing a seamless design flow from purely mathematical analysis down to the final implementation of the SDR. In a case study of an exemplary selected physical layer processing the usefullness of the workbench is highlighted.
