Proportionate-type Normalized Least Mean Square Algorithms by Kevin Wagner,Milos Doroslovacki

By Kevin Wagner,Milos Doroslovacki

The subject of this booklet is proportionate-type normalized least suggest squares (PtNLMS) adaptive filtering algorithms, which try and estimate an unknown impulse reaction via adaptively giving earnings proportionate to an estimate of the impulse reaction and the present measured errors. those algorithms supply low computational complexity and quick convergence occasions for sparse impulse responses in community and acoustic echo cancellation functions. New PtNLMS algorithms are constructed by means of identifying earnings that optimize user-defined standards, comparable to suggest sq. errors, constantly. PtNLMS algorithms are prolonged from real-valued signs to complex-valued indications. The computational complexity of the awarded algorithms is examined.
