| 摘要: |
| 跳频(FH)是提高通信可靠性的有效方法之一.介绍了一种简单实用的电力线跳频通信系统实现方案,该系统分为发送部分和接收部分,采用分路匹配滤波法实现解调.设计了电力线跳频通信系统的位同步、帧同步和跳频图案的同步方法.位同步模块与解调模块在现场可编程门阵列(FPGA)中共用一个匹配滤波解调器;其中,住同步采用超前、滞后同步法.在实验室电网环境下对设计的系统进行了误码率测试,结果表明:在通信距离不超过100 m情况下测试其误码率,编码前在1.5%以下,编码后没有发现误码情况. |

| Abstract: |
| FH(Frequency-Hopping) is an effective way to improve the reliability of communication system. A simple and practical scheme of power line frequency-hopping communication system is provided,which is divided into the sending section and the receiving section. The matched filter technology is adopted in demodulation. Its bit synchronization,frame synchronization and FH pattern synchronization are designed. The bit synchronization module and the demodulation module share a matched filter demodulator in FPGA (Fi... |
