Geometric-Algebra Adaptive Filters
Wilder B. Lopes, Cassio G. Lopes
This paper presents a new class of adaptive filters, namely Geometric-Algebra Adaptive Filters (GAAFs). They are generated by formulating the underlying minimization problem (a det…

Combination of LMS Adaptive Filters with Coefficients Feedback
Luiz F. O. Chamon, Cassio G. Lopes
Parallel combinations of adaptive filters have been effectively used to improve the performance of adaptive algorithms and address well-known trade-offs, such as convergence rate v…

Geometric-Algebra LMS Adaptive Filter and its Application to Rotation Estimation
Wilder B. Lopes, Anas Al-Nuaimi, Cassio G. Lopes
This paper exploits Geometric (Clifford) Algebra (GA) theory in order to devise and introduce a new adaptive filtering strategy. From a least-squares cost function, the gradient is…
