文档介绍:基于FPGA的数字调制系统设计
摘要
在科学技术迅速发展尤其是在通信领域以及电子信息方面的发展更为突出的今天,设计者需要一个高速通用硬件平台来实现并验证自己的通信系统和相关算法。FPGA(现场可编程门阵列)作为一种大规模可编程逻辑器件,体系结构和逻辑单元灵活、集成度高、适用范围宽,并且设计开发周期短、设计制造成本低、开发工具先进并可实时在线检验,广泛应用于产品的原型设计和产品生产。
与传统的DSP(数字信号处理器)或GPP(通用处理器)相比,FPGA在某些信号处理任务中表现出非常强的性能,具有高吞吐率、架构和算法灵活、并行计算、分配存储以及动态配置等优势,因此非常适合用于设计验证高速通信系统的基带处理部分。
基于FPGA的通信系统基带设计验证平台采用大容量、高性能的FPGA器件,为通信系统的基带设计提供了一个有效的硬件实现平台。基于FPGA的实现和验证与计算机仿真相结合,将大大加速通信系统基带部分的快速原型设计,极大地方便了对实时性和运算量有较高要求的各类算法的验证。
本论文主要是基于FPGA的硬件开发平台,通过数字调制(FSK)技术调制,再由曼彻斯特编码加密,最后再在QuartusII软件上仿真,目的是将一组信号数据发送出去。
关键词:FPGA ,FSK,曼彻斯特编码,QuartusII
Abstract
In science and technology are developing rapidly especially munication field and the development of electronic information more prominent today, designers need a high-speed general hardware platform to realize and verify munication system and related algorithm. The FPGA (field programmable gates array) as a large-scale programmable logic devices, the system structure and logic unit, flexible, integration, and wide application scope of short development cycle, design and manufacture of low cost, development tools and on-line inspection can be advanced, the product is widely applied in the prototype design and production.
And the tradition of DSP (digital signal processor) or GPP (gm), FPGA processor in some signal processing tasks shows very strong performance, high throughput, architecture and algorithm, puting and storage and distribution of the dynamic configuration advantages, therefore is very suitable for high-munication system design verification processing parts. Baseband
munications system based on FPGA baseband design verification platform using the large capacity and high performance FPGA device munication system, the baseband design provides an effective realization of hardware platform. Based on FPGA and validation puter munication system will be greatly accelerated, rapid prototyping design part baseband, great place for real-putation and show the algorithm has higher requirement of the vali
