电力线通道经常受到电器产生的脉冲干扰。因此，电力线通信由于这种脉冲干扰而劣化。我们将Middleton的A类噪声模型引入到脉冲噪声环境的统计模型中。在本文中，我们将 LDPC（低密度奇偶校验）码和和积解码应用于加性白 A 类噪声 (AWAN) 通道。我们提出了一种适用于 AWAN 通道的和积解码。此外，我们通过计算机模拟展示了所提出的和积解码在 A 类噪声环境中的 BER（误码率）性能。
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.
