Baseband Transceiver Design of a 128-Kb/S Power-Line Modem for Household Applications

Communication using a power line as a medium provides a convenient and inexpensive way for data transmission and control signaling in households. This paper introduces a power-line channel model as well as architecture of a spread-spectrum baseband transceiver IC for a power-line modem. The modulation and spreading scheme used in the proposed transceiver is mary biorthogonal keying (MBOK). This transceiver runs at a chipping rate of 256 KHz and provides 128-kb/s data rate. Simulation results and FPGA emulation verify the effectiveness of the architecture for household data communication.
