Subspace modelling for structured noise suppression

Zhiqiang Xu, Laura Rebollo - Neira, A. Plastino

    Research output: Contribution to journalArticlepeer-review


    The problem of structured noise suppression is addressed by i)modelling the subspaces hosting the components of the signal conveying the information and ii)applying a nonlin- ear non-extensive technique for effecting the right separation. Although the approach is applicable to all situations satisfying the hypothesis of the proposed framework, this work is motivated by a particular scenario, namely, the cancellation of low frequency noise in broadband seismic signals.
