Abstract
A method for packing data over a power line communication channel is disclosed herein. The method comprises packing data into symbol body, adding a first pad in front of the symbol body to form a full symbol and determining the time instance in which the peak absolute voltage point of the AC electric power occurs. And subsequently it is to send the full symbol through the power line in a manner synchronized with the time instance aforesaid. Based on the interference condition detection, the invention allows receiver side adaptation.
