Coded CP-SC communication scheme for outdoor power line communications

In this paper, we consider a cyclic prefixed single-carrier communication scheme with frequency domain equalization (CP-SC) and low-density parity check code (LDPC) over power line communication (PLC) channel. The aim is to evaluate the error performance when the PLC channel is corrupted by impulsive noise. The simulation results show that the best performance is obtained when the LDPC code is considered in association with the frequency domain equalizer based on the MMSE criterion. Additionaly, comparative results between the CP-SC and SC-DFE are presented. The results indicate that CP-SC with FDE-MMSE offer better performance than SC-DFE. Moreover, we present a simulation result that indicates that if the channel decoder has correct information about the impulsive noise variance, then error performance improvements can be obtained.
