摘要：

This paper investigates preprocessing for mitigating the impulsive noise encountered in power line communications (PLC). In particular, we consider the scenario of using powerful polar codes in the presence of Middleton Class-A Noise (MCAN). Two preprocessing methods, including blanking and clipping, are investigated before the use of successive cancellation list (SCL) decoding. With a Markov chain modeling for MCAN, the blanking is demonstrated to be an effective method for discriminating the state of MCAN and it simply erases the channel when the corrupted state due to the presence of impulsive noise is detected. The use of blanking, along with the loglikelihood ratio computation, could achieve significant gain for SCL decoding of polar codes over PLC channels, which is validated by extensive experiments.
