摘　　要：根据物联网应用背景和技术需求,设计了基于MAX2830和FPGA的无线通信系统架构。针对射频收发电路,采用MAX2830零中频电路方案实现2.4 GHz的信号收发电路;针对数字基带处理单元,在FPGA上进行通信算法优化移植研究,设计了开放式的自有协议,其兼容BLE通信协议,免于授权。对系统性能的测试验证了平台的可行性,最大发射功率达19.73 dBm,接收灵敏度达-88 dBm,支持的频偏范围符合接收需求。基于此软件无线电平台可以动态重建通信体制和模式,适用于多种通信场景,具有重要工程应用及研究价值。According to the application and technical requirements of IoT, a wireless communication architecture based on MAX2830 and FPGA is designed. For RF transceiver circuit, MAX2830 zero IF circuit is adopted to realize 2.4 GHz signal transceiver circuit. For the digital baseband processing unit, the communication algorithm is optimized and transplanted on FPGA, and the open proprietary protocol and the BLE communication protocol are designed and implemented, which are free from authorization. The system performance test verifies the feasibility of the platform. The maximum transmission power is 19.73 dBm, the sensitivity is -88 dBm, and the supported frequency offset range meets the reception requirements. Based on the software radio platform, the communication system and mode can be dynamically reconstructed, which is applicable to a variety of communication scenarios and has important application and research value.
