Abstract : The specificity of xDSL (Digital Subscriber Line) and PLC (Power Line Communications) systems lies in the fact that they reuse the existing networks such as telephonic infrastructure and power line network. These techniques have the significant advantage of optimizing the use of these media of communication. Nevertheless, those last were not initially intended to transmit high bit rate signals and their use at higher frequencies involves some problems of Electromagnetic Compatibility (EMC). This way the main concern of this PhD work consists in studying EMC aspects in wire networks that support high bit rate signals, considering the physical characteristics of the various media of transmission. Some innovative solutions are proposed for reducing crosstalk in multiconductor telephonic networks transmitting xDSL signals and for improving the transfer function of power line networks supporting PLC systems.
