Abstract :
The multidelay block frequency domain (MDBFD) adaptive filter with the two-dimensional optimum block (TOB) algorithm are extended to the Hartley domain. The convergent behaviour of the MDBHD-TOB is the same as its frequency domain counterpart while computational complexity is reduced to offer simpler implementation. Because of its computational efficiency, the MDBHD-TOB adaptive filter is well suited to applications which demand the use of a long adaptive filter, as in acoustic echo cancellation
