Abstract

The intelligent energy meter designed by us is basically a digital energy meter, which uses single-phase energy metering IC. This metered reading is brought to the database of electricity board through the” echo model”, which is identified as a suitable model for the house hold power lines among the existing power line channel models .This is followed by studies on the utilization of different robust spread spectrum techniques like code division multiplexing (CDM), Orthogonal frequency division multiplexing (OFDM) and COFDM (Combined) for data communication over the selected channel model. The results of the study are conducted, particularly in respect of bit error rate (BER) performance and spectral efficiency.
