Abstract

Multicarrier modulation techniques have been proposed for digital subscriber line (DSL) applications. The performance of DMT (OFDM) and DWMT (DSBMT) techniques for single and multitone interference are investigated. It is shown that a DMT system is sensitive to the location of narrow band interference. The DMT technique needs additional narrow band interference canceller before the forward FFT transform for performance improvements. In the DSBMT technique, due to a limited spectral overlap between its subcarriers, single (multi)-tone interference could affect only a few subchannels which correspond to these interferences. The DSBMT has a superior performance than DMT. © 1998 IEEE.
