摘　　要：软件无线电是以一个通用、标准、模块化的硬件平台为依托,通过软件编程来实现无线电台的各种功能,从基于硬件、面向用途的电台设计方法中解放出来。随着微电子技术和电子设计自动化(EDA)技术的迅速发展,以FPGA为代表的可编程逻辑器件凭借其设计方便灵活和校验快等特点广泛应用于数字信号处理领域。以软件无线电为平台,提出基于FPGA的数据传输系统基带处理单元的具体方案,并在QuartusⅡ软件中建立基带处理单元的设计实例。Software radio is based on a generic, standard and modular hardware platform to implement various functions of a radio station through software programming by getting out of hardware-based and application- faced of the radio design mind. With the rapid development of microelectronic technology and electronic design automation （EDA）, programmable logic devices represented as FPGA are widely used in the field of digital signal processing for its virtue of flexible and convenient design and quick calibration. This paper will p forward specific programs of FPGA-based baseband processing unit in data transmission system on the software radio platform the and establish design examples of baseband processing unit in Quartus Ⅱ.
