摘要:
USRP 作为软件无线电外设的杰出代表,因其价格较低,通用性好、性能强大等特点,受到了无线电研究者和 爱好者的广泛关注。文章介绍了 USRP2 母板及RFX2400 射频子板的硬件结构、主要芯片及配置方法。采用底层开发的方式, 在 USRP2 平台上实现了带宽为 12.5MHz,速率为 2.5Mbps 的 ChirpBOK 扩频发射机设计,为在 USRP 平台上进行大带宽信号通 信系统设计进行了新的尝试
Abstract:
USRP as the outstanding representative of software radio peripheral are widely concerned by researchers and enthusiasts of radio because of its low price, good versatility, powerful performance and other characteristics. This paper introduces hardware structure, the main chip and configuration method of the USRP2 motherboard and the RFX2400 RF board. Low level developed USRP2 to achieved CSS (Chirp Spread Spectrum) transmitter, which bandwidth of 12.5MHz, rate of 2.5Mbps.This design is a new attempt for the large bandwidth signal communication system on USRP platform
