Abstract

In this paper, we analyze and propose spatially coupled low-density parity-check (SC LDPC) codes for power line communications (PLC). With windowed-sequential encoding and decoding characteristics of SC LDPC codes, the low latency error correction with superior performance becomes the cornerstone for proposing these codes for PLC systems. The communication channels in PLC have impulsive noise, we use Bernoulli-Gaussian model which has heavy tail distribution for this channel. Through computer simulations, we compare these codes with block LDPC codes and show that SC LDPC codes perform better due to connectivity between coupled blocks.
