Comparison of several frequency-domain LMS algorithms

In this letter, we investigate and compare several frequencydomain LMS adaptive algorithms. These are Dentino's LMS (DLMS) algorithm, the Fast LMS (FLMS) algorithm, and the proposed Optimal FLMS (OFLMS) algorithm. Computer simulations are carried out to evaluate these algorithms under different conditions. It is shown that the OFLMS produced excellent results, particularly in the case of colored-noise excitation.
