Abstract

In the embodiment of power line modem, the important elements are selection of a suitable line-coupler, choice of a modulation method good for channel environments, and an efficient data coding method etc. In this paper an appropriate modulation method was implemented their results in details and verified by the simulations. The data compensation request techniques that uses error checking was discussed. Finally, application of other modulation method by detection of error rate per bit according to vary of channel error caused by electric equipment that is connected to power line was studied.
