Abstract :
We present a novel method for jointly optimizing FIR filters for pre-equalization, decision feedback equalization, and near-end crosstalk cancellation. The unified optimization problem is a linear program, and we describe sparse matrix techniques for its efficient solution. We illustrate our approach with uni- and bi-directional buses using differential signaling in both intra-board and cross-backplane scenarios.
