| 摘要: |
| 随着无线传感网络技术的不断发展，面向不同应用场景的单协议通信系统已满足不了各种应用场景的需求，如远距离或者高速率等。充分利用IEEE802.15.4标准的远距离和IEEE802.15.6标准的高速率特征，采用GNU Radio+USRP软件无线电平台来实现双协议互补无线通信功能，主要工作包括两种协议的媒体访问控制层和物理层的帧结构和数据编解码、前向纠错、误帧检测、帧同步与调制解调等部分的解析与功能实现。在此基础上进行了基于GNU Radio+USRP平台下双协议通信功能的验证，证明了该系统的可行性。 |

| Abstract: |
| With the continuous development of wireless sensor network technology,single-protocol communication systems for different application scenarios can no longer meet the needs of various application scenarios,such as long-distance or high-speed.By making full use of the long-distance characteristic of the IEEE802.15.4 standard and the high-rate characteristic of the IEEE802.15.6 standard,the GNU Radio + USRP software radio platform is used to achieve dual-protocol complementary wireless communication functions.The main work includes analysis and functional realization of the frame structure of the media access control layer and the physical layer,data encoding and decoding,forward error correction,error frame detection,frame synchronization,modulation and demodulation modules and other parts.On this base,the dual-protocol communication function based on the GNU Radio + USRP platform is verified and the result proves the feasibility of the system. |
