UWB标签定位系统接收机基带部分的FPGA实现

脉冲无线电(IR-UWB)技术利用极窄脉冲传输良好的时间分辨率特性,可以为收发机之间提供精确的距离测量,从而为室内与室外的定位系统提供一种低成本、高精确度的定位技术。本文对一种UWB标签定位系统作了简单的介绍,提出了一种UWB能量检测接收机的方案,并对能量检测接收机中的积分窗作了一种新颖合理的设计,简化了接收机的同步捕获模块。最后还对接收机FPGA基带处理部分作了仿真,给出了仿真波形。仿真结果证实了设计的可行性,说明UWB定位厘米级的精度是可实现的。

The FPGA Implementation of the Receiver Baseband Part of the UWB Tag Position System

The IR_UWB technology for the nicer characteristics of time differentiation rate by using very narrow impulse transmission,can provide accurate distance measuring between the transmitter and the receiver,and thus provide a low-cost but high-precision location technique for indoor and outdoor locating systems. This paper gives a brief introduction of the UWB tag location system,proposes a project for the UWB energy detecting receiver,and gives a novel and rational design of the integral window in it,which si...
