Abstract

We present results on the development of crosstalk cancellation techniques for OFDM systems. Using over-sampling and subspace principles, the crosstalk symbols and/or the null space of the crosstalk channel matrix are identified. Accordingly, two subspace-based crosstalk cancellation methods are proposed and their performances are evaluated through simulation.

Keywords: crosstalk cancellation; subspace; OFDM; DMT
