摘　　要：以低压电力线作为媒介进行数据传输时,提高其传输的可靠性对低压电力线载波通信有重要意义。针对低压电力线信道所具有的时变性和强干扰性,提出了新的抗干扰方案,即采用卷积码直接序列扩频通信方案,并使用MATLAB对该方案的抗干扰性能进行了仿真验证。结果表明,该方案能较好地抑制低压电力线信道中的干扰,满足低压电力线通信要求。Increasing the reliability of transmission has important meaning for low-voltage power line carrier communications when the data is transmit- ted based on low-vohage power line channel. Aiming at temporal variation and powerful interference of the low-voltage power line channel, the article raises the new precept for anti-jamming, which the spread-spectrum communication adopts encoding and decoding arithmetic. The anti-jamming capa- bility of the precept is validated by the MATLAB emulate. The precept can control the interference of the low-voltage power line channel better, which contents the request of the low-voltage power line carrier communications.
