Performance Comparison of Different Powerline Telecommunication Architectures

Nowadays many manufacturers are looking for new last mile techniques to bridge the gap laying between the providers and the end-users, because they naturally want to pare down the huge expenses that come from laying down new cables to all the households. This is why great investigations are made to explore all the secrets of one of a new last mile solution: the power line. In this paper we will compare three already proposed Power Line Telecommunication (PLT) systems to help these investigations as far as possible. These systems work with different multiplexing techniques, such as Orthogonal Frequency Division Multiplexing (OFDM), and two types of Code Division Multiplexing (CDMA): one is Direct Sequence (DS) CDMA, the other is Multi Carrier (MC) CDMA. We will give the description of these systems, followed by the results of the simulations we made.
