Functional Analysis of a SDR Based Bluetooth/HiperLAN Terminal Demonstrator

چکیده
In our Software Defined Radio (SDR) project we aim at combining two different types of standards, Bluetooth and HiperLAN/2 on one common hardware platform. HiperLAN/2 is a high-speedWireless 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 re-programmable and re-configurable by software in order to cope with its multiservice, 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 used in the sequel of the project for a number of purposes, of which we mention 1. Definition of reference points (for requirements definition purposes). 2. Definition of interfaces (potential alignment with SDR Forum). 3. Delimitation of our demonstrator (what is it that is going to be built). 4. Identification of inter-standard functional integration. challenges. Keywords—Software Defined Radio, Bluetooth, HiperLAN/2, Functional Modelling, Functional Architecture

A Bluetooth-enabled HiperLAN/2 receiver
In our SDR project we aim to combine a GFSK receiver (Bluetooth) with an OFDM receiver (HiperLAN/2). Other WLAN standards use the same frequency bands and modulation techniques. So our Bluetooth-enabled HiperLAN/2 receiver can easily be adapted to other WLAN standards. This paper focusses on the integration of the two receivers. A functional architecture of a combined receiver and its computati...
متن کاملAn Analogue Front-End Architecture for Software Defined Radio
A Software Defined Radio (SDR) is a radio receiver and/or transmitter, whose characteristics can to a large extent be defined by software. Thus, an SDR can receive and/or transmit a wide variety of signals, supporting many different standards. In our research, we currently focus on a demonstrator that is able to receive both Bluetooth and HiperLAN/2. This helps us to identify problems associate...

In our Software Defined Radio (SDR) project we aim at combining two different types of standards, Bluetooth and HiperLAN/2 on one common flexible hardware platform. The HiperLAN/2 hardware is that complex compared to the Bluetooth hardware, that Bluetooth capability may be added to the HiperLAN/2 platform at limited cost. The question is how to do this. In this paper we first describe the radio...
