摘要
为了能更好地研究和验证认知无线电相关技术和算法,本文提出一种嵌入式认知无线电实验平台的设计方案。该实验平台采用ARM+FPGA的双处理器结构,主要分为射频、基带处理和嵌入式控制3大部分。ARM作为主处理器,运行嵌入式Linux操作系统,负责整个通信系统的工作控制以及人机交互的工作;FPGA作为数据处理核心,主要负责对基带信号的处理、算法实现以及射频模块的配置工作。系统采用液晶触摸界面,使用灵活方便,可在脱离PC机的情况下工作,为认知无线电技术的研究工作提供了好的硬件平台。
In order to study and verify cognitive radio techniques and algorithms, an embedded cognitive radio platform is proposed. The platform uses dual-processor architecture of ARM ＋ FPGA. It is divided into three parts of RF, baseband processing and embedded control As main processor, ARM runs the embedded Linux system and is responsible for the work of system con- trol as well as the work of interaction. As data processing core, FPGA is responsible for the baseband signal processing, algorithms and RF module configuration. The platform is used flexibly with LCD touch screen. It can work without PC. It provides a good hardware platform for the study of the cognitive radio technology.
