| Abstract: |
We propose an equalization algorithm that employs multiple decision-feedback equalizers (DFE)s operating in different directions and arbitration among the outputs of these equalizers to mitigate the effects of two-dimensional intersymbol interference (ISI). The multi-directional arbitrated DFE (MAD) exploits directional diversity to reduce the effects of error-propagation while maintaining complexity on the same order as a DFE. Simulation results show that, when four DFEs are used, the MAD algorithm can achieve substantial gains over a single DFE, including gains of over 10 dB at $10^{-2}$ BER for simulations in this paper. |
