Abstract

Blind channel identification methods based on the over-sampled channel output is a problem of current theoretical and practical interest. In this contribution, it is first demonstrated that the subspace methods developed in [1] are not robust to errors in the determination of the model order. An alternative solution is then proposed, based on a linear prediction approach. The effect of overestimating the channel order is investigated by simulations: it is demonstrated that the prediction error methods is 'robust' to over-determination, in contrast to most of the schemes suggested to date.
