Abstract :
The issue of load impedance characterization in the residential environment is addressed in this work. The transfer function of any point-to-point link on any indoor power line network depends on the communications characteristics of the medium and the presence of residential loads, in the form of electrical appliances. Measurements of the transfer function variations on an experimental setup, caused by an unknown residential load, can be exploited to determine the value of its impedance. In this paper, we propose two new methods of impedance identification and analyze their accuracy and performance limitations.
