In order to validate the modelling assumptions against the real physical world the high-level functional model needs to be translated into a prototype. A systematic system design methodology proves very valuable since it avoids or at least reduces numerous design iterations. In this paper we propose a novel Matlab-to-hardware design flow which allows to map the algorithmic functionality onto the target prototyping platform in a systematic and reproducible way. The proposed design flow is partly manual and partly tool assisted. It is shown that the proposed design flow allows to use the same testbench throughout the whole design flow and avoids time-consuming and error-prone intermediate translation steps.

INTRODUCTION Fourth generation high-throughput HT wireless local area networks WLANs which are currently being standardized in the IEEE 802.11n Working Group 1 aim for higher data rates well beyond 100 Mbps effective throughput at the medium access control MAC service access point SAP larger range and better quality-of-service QoS compared to existing IEEE 802.11a g type of WLANs. To meet these ambitious targets it is now widely agreed upon that both the physical PHY and the MAC layer of these .
