Adaptive Signal Processing with Emphasis on QRD-Least Squares Lattice

An adaptive filter is a signal processing device that is self-designing in that the adaptive filter relies for its operation on an iterative algorithm. The algorithm makes it possible for the filter to perform satisfactorily in an environment when complete knowledge of the relevant signal characteristics is not available [1], Adaptive filters find applications in such diverse fields as communications, radar, sonar, control, and biomedical engineering.
