In the gradient lattice algorithm, the forward and backward prediction errors are given by (13.4.102).

(a) Show that the minimization of the least-squares error

with respect to the reflection coefficients results in the equation given by (13.4.103).

(b) To determine an equation for the recursive computation of the reflection coefficients given by (13.4.103) define
