电力载波信道的扩频通信技术

Spread Spectrum Communication in Electric Power Line

针对电力线通信中,载波频率不高,传输信息量少,时延要求不是很严格,抗干扰要求较高等特点,提出了一套数字化扩频通信捕捉、跟踪方案,结合现代通信技术与数字信号处理技术,对传统的扩频通信进行改进,有效提高其传输准确率。

Aiming at Carrier frequency lower, information not large, delay not quite accurate and anti-jamming require strict, the thesis proposes a solution about digital acquisition and tracking in Spread Spectrum Communication in electric power line, contacting with modern communication and digital signal processing technique, which makes the improvement to the traditional Spread Spectrum Communication, and effectively enhances its transmitting accurate rate.
