The authors develop an analytical framework to evaluate the probability-of-miss and probability-of-false-alarm performance of an Impulse Noise (IN) detection algorithm for Orthogonal Frequency-Domain Multiplexing (OFDM) symbols based on monitoring the post-Frequency-domain-EQualizer (FEQ) instantaneous error at the output of the QAM constellation de-mapper over a range of tones (sub-carriers). Using the VDSL system as a reference, they further analyze the impact of impulse-noise detection error events at the scale of the OFDM symbol (miss and false alarm) on the Bit-Error-Rate (BER) performance of interleaved Reed-Solomon (RS) codes with erasure-decoding.
