Abstract

In powerline communication systems (PLC), suppression of impulsive noise is a challenging problem. One of the existing methods to mitigate impulsive noise is a deliberate blanking which removes the received samples that exceed a given threshold. However, if the received signal amplitude exceeds the blanking threshold, it may cause miss-detection of impulsive noise. Therefore, it is important to determine the blanking threshold properly. In this article, we theoretically analyze the impact of the blanking threshold selection on achievable performance, i.e., probability of impulsive noise detection (PoD), probability of false alarm (PoF), and bit error rate (BER) in multi-carrier PLC systems.
