Description

technical field

[0001] The invention relates to the technical field of simulation of communication systems, in particular to a system for simulating communication between nodes. Background technique

[0002] Power line carrier communication (PLC) refers to the communication method using the power line as the transmission medium. It is mainly used in: remote automatic meter reading, automatic control of distribution network, interconnection within the home, intelligent community and last mile network access of multimedia communication, etc. In recent years, the development of broadband power line communication technology has improved the data transmission rate of power line communication, especially the development of orthogonal frequency division multiplexing technology has enabled the realization of high-speed PLC.

[0003] The remote automatic meter reading system using power line broadband carrier communication technology is a fully automatic meter data acquisition commun...
