Evaluation of the Time-Domain Speech Enhancement Filters

So far, all the chapters have been dealing with the derivation of optimal filters for speech enhancement from a subspace perspective. In this chapter, we present evaluations of the time-domain versions of these filters for both single-channel as well as multichannel scenarios. First, we evaluate the single-channel scenario, where we consider both the case where the rank of the correlation matrix of the desired signal is less than the filter length and the case where it is full rank. Then, we proceed to evaluate the time-domain multichannel filters.
