3G移动终端基带信号处理器设计与实现 摘要：随着数字技术的进步，高速、超大规模集成电路广泛使用，3G移动终端基带信号处理系统正朝着灵活、高度集成化、模块化、通用化的方向发展。基带信号处理器是数字技术与通信技术相结合的产物，它能灵活处理数字基带信号，调制无线信号以便实现同通信网络系统前端基站的无线通信。文章设计了一种基于先进微处理器(ARM)、数字信号处理(DSP)和现场可编程门阵列(FPGA)体系结构的3G移动终端基带信号处理器。这种体系结构的优点在于当提供更能满足客户需求的先进处理器时，整个系统容易集成，而且可以通过软件方法方便地增加功能，而不必定制只读存储器(ROM)编码的新芯片。同时系统使用软件实现联合检测和信号解码功能，通过软件更新轻松实现对系统的任何升级，无需硬件修改。 关键字：3G，信号处理 Design and Realize of 3G Mobile Termination Baseband Signal Processor ABSTRACT:Along with digital techniques progress, high speed, the ultra large scale integrated circuit widely uses, the 3G mobile termination baseband signal processing system toward nimble, integrated, modular, the universalized direction is developing highly. The baseband signal processor is the product which the digital technique and the communication unify, it can process the digital baseband signal nimbly, the modulation wireless signal in order to realize with the communication network system front end the base depot wireless communication. along with digital techniques progress, high speed, the ultra large scale integrated circuit widely uses, the 3G mobile termination baseband signal processing system toward nimble, integrated, modular, the universalized direction is developing highly. The baseband signal processor is the product which the digital technique and the communication unify, it can process the digital baseband signal nimbly, the modulation wireless signal in order to realize with the communication network system front end the base depot wireless communication. The article has designed one kind based on advanced microprocessor (ARM), digital signal processing (DSP) and scene programmable gate array (FPGA) the architecture 3G mobile termination baseband signal processor. This kind of architectures merit lies, when provides can meet the customer need the advanced processor, the overall system easy to integrate, moreover may increase the function conveniently through the software method, but does not need to have custom-made the no
