这是一本国外的经典教材，讲述了现阶段所有数字信号处理的FPGA实现，从第二章讲述二进制的算法到现阶段数字信号处理的研究热点，基于FPGA实现！包括FIR，自适应滤波，纠错码，调制解调，加密，傅立叶变换等等。更难能可贵的是每个例子都有VHDL和Verilog代码！！(This is a classic foreign materials, described at this stage all the digital signal processing FPGA, from the second chapter about the binary digital signal processing algorithms to the current stage of research focus, based on FPGA implementation! Including FIR, adaptive filtering, error-correcting codes, modulation and demodulation, encryption, Fourier transform and so on. Even more valuable is that each case has a VHDL and Verilog code! !)

车载诊断仪，在线OBD，ECU通信协议技术规范，是诊断仪，ECU开发者必备文档 (Car diagnostic online the OBD ECU communication protocol technical specifications, diagnostic ECU developers required documentation)

IEC103规约应用的知识要点文档，对学习iec103协议的人帮助很大(IEC103 application of the knowledge elements of the Statute of the document, to learn iec103 agreements were of great help to)

公交非接触IC卡读写器的应用设计采用PHILIPS公司的Mifare卡作IC卡，设计以射频技术为核心，以单片机为控制器的IC卡读写器在公交自动收费系统中的应用。制作的IC卡读写器可以实现制卡、售卡、自动收费等功能，具有安全、实用、方便、快捷、可靠性高的特点，解决了城市公共交通服务行业既频繁又琐碎的收费管理问题，有广泛的应用前景。(Bus non-contact IC card reader applications designed using the Philips Mifare cards for IC cards, designed to RF technology as the core, microprocessor controller IC card reader automatically charges the transit system applications. The production of IC card reader card system can be achieved, A file, automatic charges and other functions, is safe, practical and convenient, fast and high reliability features to solve the urban public transport sector is also frequent charges trivial issues, a broad range of applications.)

This document describes about the digital modulation techniques especially about spread spectrum.
