Abstract :
A new adaptive algorithm is presented for updating the parameters of normalised lattice structured recursive filters. The normalised lattice can be represented in the form of CORDIC blocks by converting the reflection factors into trigonometric functions. The LMS based algorithm actually updates the arguments of these trigonometric functions, and requires fewer computations than an earlier reported algorithm
