Single Carrier Transmission in Power Line Channels Using Time and Frequency Domain Decision Feedback Equalizations

Mohsen Sheikh-Hosseini, Mohammad Molavi

Abstract


Orthogonal Frequency Division Multiplexing (OFDM) is a suitable candidate for broadband Power Line Communications (PLC). However, OFDM systems suffer from high Peak to Average Power Ratio (PAPR), subcarriers synchronization. It has shown that single carrier transmission with frequency domain equalization is an alternative technique for OFDM in broadband wireless systems. In this paper we describe different categories of single carrier systems and investigate the BER performance of single carrier PLC systems employing time and frequency domain decision feedback equalization techniques, and convolution coding. The distractive factors like impulsive noise and multipath effects are taken into account. The results of our simulations are compared with OFDM systems.
