Multidelay block frequency adaptive filter
WebAn overview is presented of several frequency-domain adaptive filters that efficiently process discrete-time signals using block and multirate filtering techniques. These algorithms implement a linear convolution that is equivalent to a block time-domain adaptive filter, or they generate a circular convolution that is an approximation.

http://signal.ee.bilkent.edu.tr/defevent/papers/cr1373.pdf Webthe usefulness of the NBLMS and its frequency-domain variations FBLMS. A major problem of FBLMS in AEC application is the long delay associated with the large filter size. Soo proposed a variation of FBLMS, which was referred to as the multidelay block frequency domain adaptive filter (MDF) to alleviate this delay trouble [4].
