Abstract

Power line channel often suffers from impulsive interference generated by electrical appliances. Therefore, power line communication makes degradation due to such impulsive interference. We introduce Middleton's Class A noise model into a statistical model of impulsive noise environment. In this paper, we apply LDPC (Low Density Parity Check) codes and sum-product decoding to additive white Class A noise (AWAN) channels. We propose a sum-product decoding which is suitable for AWAN channels. In addition, we show the BER (Bit Error Rate) performance of the proposed sum-product decoding in Class A noise environment by computer simulation.
