A DFE coefficient placement algorithm for sparse reverberant channels

Research output: Contribution to journal › Letter › peer-review

Abstract

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.
