The increasing needs for higher data rates associated with mobility constraints motivates the development of the fourth generation of wireless systems. In this paper we focus on rapid prototyping of such emerging software radio applications. To address this problem, we propose a five steps methodology based on both an Electronic System Level (ESL) design tool and a High Level Synthesis (HLS) tool. The methodology has been applied on the design of a Multiple Input Multiple Output (MIMO) system using orthogonal space time codes.
