Turbo decoding in impulsive noise environment

Power line channels often suffer from impulsive interference generated by electrical appliances. Therefore, power line communication (PLC) degrades due to such impulsive interference. Middleton´s class A noise model is frequently utilized for the modeling of such impulsive noise environments. We deal with turbo decoding for turbo codes over an additive white class A noise (AWAN) channel. We propose a turbo decoding which is suitable for AWAN channels. In addition, we show the BER (bit error rate) performance of the proposed turbo decoding in a class A noise environment by computer simulation.
