A solution to indoor power line input impedance and transfer function

Indoor power line communication with the economy, convenience and other benefits has been got a growing number of applications. So it has the important theoretical research value to solve indoor power line input impedance and transfer function with an easy and accurate way. Based on transmission-line theory, and taking multi-node power line network equivalent phantom as the research object, we calculate the equivalent input impedance of circuit and analyze the transfer function of network with transmitted parameter matrix. Being simulated and verified, the digital conclusion we got from this paper is accurate and correct, which means the method being used is correct and effective.
