Zusammenfassung:We propose a scheme to improve system performance in Discrete MultiTone systems, which combines the joint differential and common mode processing at the receiver side with erasure marking. This is achieved by using the strong correlation between differential and common mode in the case of a few strong interferers to obtain an estimate of the impulse noise or RFI, which is used for error localization before decoding. When side information is available, a Reed Solomon (RS) decoder is able to correct twice as many erasures than errors.
