无线传感器网络环境下UWB系统的SOPC协同设计平台

SOPC Co-Design Platform for UWB Systems in Wireless Sensor Network Context

Daniela Dragomirescu, Aubin Lecointre, Robert Plana

摘要:

本文提出了无线传感器网络无线接口问题的解决方案。我们介绍了无线传感器网络的上下文和相关的约束。我们提出了一个IR-UWB的解决方案,并说明为什么它可能是一个可行的无线传感器网络的解决方案。提出了一种基于Matlab的IR-UWB无线接口高层建模与仿真平台。它使我们能够根据BER与Eb/N 0标准和WSN约束确定什么样的设计更合适。提出了一种基于Matlab VHDL的协同设计协同仿真平台。利用该平台设计了具有数据率重配置、跳时码重配置、频谱占用重配置和无线电距离重配置等功能的IR-UWB收发机。

英文摘要:

This paper presents our approach of the radio interface problematic for Wireless Sensor Network. We introduce the WSN context and constraints associated. We propose an IR-UWB solution and illustrate why it could be a viable solution for WSN. A high level modelling and simulation platform for IR-UWB radio interface is proposed on Matlab. It allows us to determine according to BER versus Eb/N0 criteria and the WSN constraints what kind of design is more adequate. Moreover, a co-design co-simulation platform Matlab VHDL is proposed here. Using this platform we designed IR-UWB transceiver having reconfigurable capabilities, such as data rate reconfiguration, time hopping code, spectrum occupation and radio range reconfiguration.
