基于FPGA的扩频通信芯片设计及应用
摘要
随着网络技术和通信技术的突飞猛进,人们对通信的保密性能,抗干扰能力的要求越来越高,而且对信息隐蔽、多址保密通信等特性提出了更高的要求。这些要求的实现都离不开扩频通信技术的应用,而扩频通信芯片作为扩频通信网络的核心器件,自然也成了研究的重点。本论文旨在借鉴国内外相关研究成果,并以家庭电力线通信环境为背景,验证了一种CDMA码分多址通信的实现方案,并通过智能家庭系统展示了其应用效果。
本课题以构建家庭电力载波通信网络为目标,首先,以两块Cyclone系列FPGA开发板为基础,分别作为发送单元和接收单元,构建了系统的硬件开发平台;以QuartusⅡ7.2为开发环境,运用Verilog硬件描述语言,编写扩频模块和解扩模块,并且进行了测试、仿真和综合,验证了通过专用芯片实现扩频通信系统的可行性。应用方面,采用电力线载波通信芯片,提出了一种由智能插线板和嵌入式网关构成的家电控制系统。用户通过WEB方式登陆嵌入式网关,智能插线板能够在嵌入式网关的控制下控制电器的电源、发送红外遥控指令,实现对家电的远程遥控。使用两块FPGA开发板,实现了扩频通信基本收发是本设计得主要成果;将扩频通讯技术、嵌入式Web技术引入到智能家庭系统的设计当中是本文的一个特点。
仿真和实验表明:采用电力线载波通信芯片组建家庭网络的方案可行,由智能插线板和嵌入式网关构成的家电控制系统能灵活、便捷地实施家电控制,并具有一定的节能效果。
Along with the development of networking and communication technology, people request security performance, anti jamming ability, information hiding, and multiple access privacy communication. Spread spectrum communication meets all these requests and indispensable, spread spectrum communication chips as the core device of the system, become the research emphasis as well. This paper references to the research results from domestic and aboard, and take the family power line communication as the background, proposed a code division multiple access communication implementation scheme, and has demonstrated its application through an intelligent family system.
The goal of this subject is to construct the family electric power carrier communication network with CDMA. Firstly, take two Cyclone series FPGA development board as the hardware platform, as the transmission unit and the receive unit. Use Quartus II 7.2 as the development environment, utilizing the Verilog hardware description language, design the transmission and receive module. Test has been carried on, together with the simulation and the synthesis, and has realized the bottom layer communication function.
To the aspect of application, an electrical appliances control system was proposed. In this system, the embedded gateway and the intelligence patch board communicate through the power line.
The intelligence patch board can control the power source and transmit infrared remote control instruction under the commander from the embedded gateway. The users log in the WEB page of the embedded gateway, in order to realize the electrical appliances long-distance remote control. Realizing the CDMA transmit and receive module by two Cyclone series FPGA development boards is the main achievement. Design an intelligent family system combine with power line communication, embedded WEB server, is the characteristic of this application.
The system test indicated that, by using the existing network resources, this intelligent family system can control the electrical appliances conveniently.
