Furthermore , we use the matlab simulation result to analyze the capability of viterbi decoding . finally , we complete the fpga designing of each module in the base - band processing unit , including parallel - to - serial conversion module , framing module , convolutional coding module in the sending end , serial to parallel conversion module , viterbi 基带处理单元各模块的fpga设计主要包括发送端并串转换模块、成帧模块、卷积编码模块、接收端串并转换模块和viterbi译码模块,应用quartusii5 . 1开发平台以及modelsim仿真软件,给出了仿真结果。
It has many benefits due to its ultra - wideband nature which including the following : not sensitive to channel fading , low transmit power , extremely difficult to intercept , low complexity of transceiver structure , fine range resolution ( centimeter scale ) for location and so on this paper combines uwb technology and mobile ad hoc network technology , concerting the lasn project of national key laboratory of communication , researchs the baseband process cell of uwb communication transceivers on the base of arithmetic research and spot test 本文结合uwb技术和移动自组织网( manet ,即mobileadhocnetwork )技术,配合通信抗干扰技术国防重点实验室uwb技术研究项目“ lasnproject ”的工作进展,在算法研究和现场测试的基础上,对uwb通信节点样机的基带处理单元进行设计研究。样机结构包含三大模块:天线、用分立器件形成的射频电路、由fpga构建的基带处理单元。
