摘　　要：提出一种基于PCI Express总线的多天线射频收发系统架构。系统的射频前端采用零中频结构,可支持0.3～3.8GHz的频率范围,1.5～28MHz的调制带宽以及TDD/FDD工作模式。同时,系统利用PCIe总线和高效的DMA工作机制,实现了射频收发系统与PC机之间高数据速率、低时延的数据交互。通过验证,该系统可用于实现软件无线电高速信号采集,支持多种通信协议,如LTE,802.11,CMMB,UHF-RFID等。A multi-antenna RF transceiver system architecture was proposed based on PCI Express bus, in which Zero-IF architecture was used for RF front-end to support TDD/FDD mode. The system operated in RF band between 300 MHz and 3. 8 GHz with a modulation bandwidth ranging from 1.5 MHz to 28 MHz. PCIeX 8 bus and DMA transmission mechanism were used to achieve high speed and low delay data exchange between PC and RF transceiver system. The transceiver could be used for high-speed data acquisition in software radio system, and it supports multi-protocol, such as LTE, 802. 11, CMMB and UHF-RFID.
