在进行信息传输的过程中将低压电力线作为主要的工具与媒介,因此,加强对其传输效果的可靠性进行研究就显得十分必要。结合低压电力线信道的特性,也就是时变性以及强干扰性特征,形成有效的抗干扰对策,采用卷积码直接序列扩频方式加以解决,同时也可以通过MATKAB完成对设置的仿真验证。实际结果显示,这个方案可以有效的控制低压电力线信道产生的不同干扰,并完成通信需要。
In the process of information transmission, low voltage power line is regarded as the main tool and medium, so it is necessary to study the reliability of transmission effect. Combined with the characteristics of low-voltage power line channels, that is, the characteristics of time-varying and strong interference, an effective anti-jamming strategy is formed, and the direct sequence spread spectrum method of convolutional codes is used to solve the problem. At the same time, MATKAB can also be used to verify the settings. The actual results show that this scheme can effectively control the different interference generated by the low-voltage power line channel and accomplish the communication needs.
