A 100-kbps power-line modem for household applications

Communication using power line as a medium provides a convenient and inexpensive way for data transmission and control signaling in households. In this paper we introduce a power-line channel model as well as architecture of a spread-spectrum baseband transceiver IC for a powerline modem. The modulation and spreading scheme used in the proposed transceiver is MBOK. This transceiver runs at the carrier frequency of 256 kHz and provides 100 kbps data rate. Simulation results verify the effectiveness of the proposed architecture in household data communication.
