... is introduced, employing the already available time-frequency analysis of the beamformer and the decisions made by hypothesis testing. From (4 )and( 13), we have the following input-outputrelation ... functions (ATFs). The proposed system integrates adaptive beamforming, ATF identification, soft signaldetection, and multichannel postfiltering. The noise canceller branch of the beamformer and the ATF ... signals.Let three hypotheses H0s,H0t,andH1indicate, respec-tively, the absence of transients, presence of an interfer-ing transient, and presence of a desired source transient at the beamformer...
