Abstract

Traditionally equalization is performed individually for 10GBASE-T, and FEXT is treated as noise to be cancelled at the receiver. However, FEXT contains information about the symbols transmitted from remote transmitters and it can be viewed as a signal rather than noise to facilitate signal recovery. This paper proposes to use MIMO (multi-input multi output) equalization technique to deal with FEXT in 10GBASE-T. In the proposed MIMO technique, FEXT is treated as signal, which improves SNR. Instead of using long FEXT cancellers, MIMO-DFE with short length is used to remove post-cursor ISI. Our simulation results show that, by using the proposed MIMO equalization, we are able to achieve SNR (signal to noise ratio) improvement around 0.5-9dB with 13% less complexity than the traditional equalization technique in twisted-pair channel environment.
