Zusammenfassung:We present formulations and simulation results for infinite- and finite-length MIMO decision feedback equalization and compare with finite-length SISO equalizer/FEXT canceller for an improved version of Cat-6 cable. Intuitively, far-end crosstalk contains useful information, and instead of being cancelled, could be jointly processed to improve performance. Conversely, a simpler system could be designed for a given transmission rate. A SISO equalizer/canceller is compared with a MIMO equalizer to investigate possible improvement in decision point SNR and filter lengths.
