adaptive filtering, signal processing
One of the most common problems in using of adaptive
filters is their behavior in condition of application of a
high amplitude and short time pulses at the filters’ input.
The ALMS mean filter is an OSLMS filter, featured by a
good convergence of their coefficients into optimal
values, but a low stability of the prediction coefficients.
Another OSLMS filter is the MLMS mean filter, featured
by greater prediction coefficients stability, but a lower
coefficients convergence to the optimal values.
This paper studie the properties of three algorithms
(gradient algorithm, SHARF algorithm and Steiglitz-Mc
Bride algorithm), used to compute the IIR filters
coefficients. It was studied three kind of IIR filters ( IIR,
Average-IIR and Median-IIR) implemented in direct form
and in lattice form.
