High level HW/SW Codesign as a solution for Software Defined Radio development

This paper introduces a technique to develop HW/SW radio systems based on the well-known Simulink environment. The proposed high-level language and cosimulation environment allows to quickly explore the HW/SW design space, analyze the effect of implementation choices, optimize system parameters and minimize the cost/performance ratio. As a consequence, the proposed approach significantly reduces the time-to-market. The design of the physical link of the UMTS standard is reported as a case of study
