Description :

　　The principle and characteristics of power line carrier communication: 1. Power line carrier communication refers to the technology of using existing power lines to transmit analog or digital signals at high speed through carrier methods. The most basic task in power line carrier communication systems is to select different modulation methods according to the different communication channels.

　　2. Generally speaking, baseband signals contain DC components and lower frequency components, which cannot be directly transmitted as transmission signals in the channel. Therefore, it is necessary to convert the baseband signal into a bandpass signal (modulated signal) that is very high relative to the baseband frequency to be suitable for channel transmission.

　　3. The quality of a communication system largely depends on the modulation method used. In order to match the signal characteristics with the channel characteristics during modulation, the choice of modulation method is determined by the channel characteristics in the system. Obviously, different types of channel characteristics will correspond to different types of modulation methods.
