Adaptive Lattice-Based RLS Algorithms
There are a large number of algorithms that solve the least-squares problem in a recursive form. In particular, the algorithms based on the lattice realization are very attractive because they allow modular implementation and require a reduced number of arithmetic operations (of order N) [1–7]. As a consequence, the lattice recursive least-squares (LRLS) algorithms are considered fast implementations of the RLS problem.
