In this paper, the design of a base band OFDM system for communication over Low Voltage (LV) power lines is discussed. Such a system is suitable for the development of networks at homes or small offices. With regarding 802.11b IEEE standard for wireless LAN, the system parameters are set so that transmission of coded data at 12 Mb/s is possible. The proposed system uses a 512-point conjugate symmetric block as input to the IFFT. Simulation results for the proposed system for different channel responses are presented.
