Geometric-Algebra LMS Adaptive Filter and its Application to Rotation Estimation.
IEEE Signal Processing Letters(2016)
摘要
This letter exploits geometric (Clifford) algebra (GA) theory to devise and introduce a new adaptive filtering strategy. From a least-squares cost function, the gradient is calculated following results from geometric calculus (GC), the extension of GA to handle differential and integral calculus. The novel GA least-mean-squares (GA-LMS) adaptive filter, which inherits properties from standard adap...
