This paper describes a new communication system that meets the quality of service requirements for home high speed communications. This system is based on Ultra-Wide Band (UWB) and Power Line Communication (PLC) technologies. The performances of our MBOA-PLC (Multi Band OFDM Alliance - Power Line Communication) system was evaluated by Matlab simulation to predict the efficiency of the UWB over PLC technology and their potential applications in the home network. The system compares the transmitted and received data to calculate the bit error rate (BER), based on the energy per bit to noise power spectral density ratio (Eb / N0). This is achieved by varying the number of information bits transmitted per OFDM symbol and the convolutional coding rate. The BER performance analysis presented in this study aims for a very high-speed transmission on indoor CPL channels, at more than 200 Mbps. The maximum data rate available on the market does not exceed 200 Mbps, despite the use of advanced coding and modulation systems, such as 1024 QAMs and the turbo-codes used for the Homeplug AV standard. The existing technology has little room to increase throughput because the available operational bandwidth limits the capacity of the channel.In the proposed PHY model for indoor PLC communications, QPSK mapping is used to provide good BER performance at high data rates that existing techniques have difficulty obtaining.
