| 摘 要： | 本文对低压电力线载波通信信道特性进行了实验研究，重点测量和分析了低压电力线的阻抗特性、衰减特性和噪声特性。同时，针对低压电力线载波通信信道特点，提出了一种新的调制解调算法。仿真结果证明该算法同时对宽带噪声、窄带噪声和多径干扰具有较强的抑制能力。

| Abstract: | The transmission characteristics are investigated that includes the impendence, attenuation and noise performance of the low-voltage power line carrier channel. A new modulation algorithm is discussed based on the investigated results. The simulation result shows that the new algorithm can restrain the broadband noise, narrowband noise and multi-path interfere. |

| Keywords: | power line carrier channel characteristics multi-carrier coding modulation relative judgment |
