Functional Analysis of a SDR Based Bluetooth/HiperLAN Terminal Demonstrator

摘要

In our Software Defined Radio (SDR) project we aim at combining two different types of standards, Blue-tooth and HiperLAN/2 on one common hardware platform. HiperLAN/2 is a high-speed Wireless LAN (WLAN) standard, whereas Bluetooth is a low-cost and low-speed Personal Area Network (PAN) standard. An SDR system is a flexible radio system that is reprogrammable and reconfigurable by software in order to cope with its multi-service, multi-standard and multi-band environment. Goal of our project is to generate knowledge about designing the front end of an SDR system where especially an approach from both analog and digital perspective is essential. To what extent can we use the HiperLAN/2 receiver hardware for our Bluetooth receiver? In this paper we present a functional architecture that brings the architectural descriptions of both standards to an equal level. This SDR functional architecture is usedudin the sequel of the project for a number of purposes, of which we mention ud1. Definition of reference points (for requirements definition purposes).ud2. Definition of interfaces (potential alignment with SDRudForum).ud3. Delimitation of our demonstrator (what is it that is go-uding to be built).ud4. Identification of inter-standard functional integration challenges.
