A DFE coefficient placement algorithm for sparse reverberant channels
M.J. Lopez, Andrew C. Singer · IEEE Transactions on Communications · 2001
We develop an automated algorithm for determining the number and sparsely supported locations of coefficients in a multi-element array decision-feedback equalizer based on an estimated channel response. We aim for robustness to a wide variety of possible channel conditions, especially through taking advantage of the interplay between the MMSE-optimal feedforward and feedback filters.
