软件定义无线电(SDR)是一种灵活的体系结构，可以配置为适应各种无线标准、波形、频带、带宽和操作模式。本文对现有的SDRS硬件和软件平台进行了详细的调查。给出了在MATLAB/SIMULINK环境下进行软件无线电设计和测试的原型系统，并简要讨论了认知无线电原型系统的主要功能。搭建了一个无线个域网原型系统，并与Ettus Research LLC的通用软件无线电外围设备2(USRP2)主板和RFX2400子板进行了接口。原型背后的理念是在主机(PC)上完成所有特定于波形的处理，如在主机(PC)上进行信道编码、调制、滤波等，并在USRP2上完成通用高速运算，如数字上、下转换、抽取和内插等。MatLab拥有一系列丰富的工具箱，允许构建软件定义的认知无线电，以探索各种频谱感知、预测和管理技术。
Software Defined Radio (SDR) is a flexible architecture which can be configured to adapt various wireless standards, waveforms, frequency bands, bandwidths, and modes of operations. This paper presents a detailed survey of the existing hardware and software platform for SDRs. It also presents prototype system for designing and testing of software defined radios in MATLAB/Simulink and briefly discusses the salient functions of the prototype system for Cognitive Radio (CR). A prototype system for wireless personal area network is built and interfaced with a Universal Software Radio Peripheral-2 (USRP2) main-board and RFX2400 daughter board from Ettus Research LLC. The philosophy behind the prototype is to do all waveform-specific processing such as channel coding, modulation, filtering etc. on a host (PC) and general purpose high-speed operations like digital up and down conversion, decimation and interpolation etc. inside FPGA on an USRP2. MATLAB has a rich family of toolboxes that allows building software-defined and cognitive radio to explore various spectrum sensing, prediction and management techniques.
