Abstract
A receiving circuit, a transmitting circuit, a micro-controller, and a method for power line carrier communication. The receiving circuit includes: an analog amplifier, a receiving filter, an analog-to-digital converter, a digital mixer, a digital filter, and a digital demodulator connected successively. The transmitting circuit includes: a digital modulator, a gain controller, a digital-to-analog converter, a transmitting filter, and a transmitting amplifier connected successively. The micro-controller includes a central processor and the receiving circuit or the transmitting circuit. The method for power line carrier communication can be implemented based on the receiving circuit or the micro-controller. The receiving circuit, the transmitting circuit, the micro-controller, and the method for power line carrier communication provided by present invention solve the defect of supporting only one modulation or demodulation mode in a conventional power line carrier communication system, and can process a power line carrier signal in different modulation or demodulation modes.
