Data Rate Profiles of Coded/Uncoded Power Line Channel with Single Carrier/Multicarrier Modulation Techniques

Abstract

This paper focused on determining the data rate profile achievable using the single carrier/multicarrier modulation techniques with Reed Solomon Concatenated Convolutional (RS-CC) codes for data transmission through a power line channel. Lately, electronic means of communication has gained popularity for the transfer of information. However, there is a need for more transmission medium like power line as a channel for remote data delivery. Data transmission was achieved using a parametric model of a power line channel with the various noise factored in the simulation. In the designed Power Line Communication (PLC) system, single carrier modulation offered a maximum of 14.4Mbps reduction in data rate when the uncoded 64-Quadrature Amplitude Modulation (QAM) was compared to coded 64-QAM with 1/2 Forward Error Correction (FEC). In the OFDM Power Line Communication (PLC) system, the reduction in data rate was maximum at 39Mbps when the uncoded 16-QAM was compared to the 16-QAM with 1/2 FEC. It was evident that increased code rate of the PLC system using a single carrier and OFDM modulation implied increased data rate profiles.
