Abstract :
The modified Fermat number transform (MFNT) is applied to the efficient realisation of the LMS and block LMS adaptive digital filters. The Fermat number transform (FNT) had earlier been used to implement the BLMS. It is shown that the MFNT leads to more computationally efficient realisations of the LMS and BLMS adaptive filter than the FNT.
