Algorithm 1
The pseudocode of the iterative process in RIAA.
Algorithm RIAA | Initialization | Use (6) to obtain the initial estimates and in . | The First Iteration | Obtain using (16) with parameters and given by . Obtain using (22). Using | and to drive the first weighted matrix by (15). Update estimate by (19) with = . | Updating Iteration | At the iteration, = , estimates and are iteratively updated in the same way | as the first iteration. | Termination | Terminate simply after 15 iterations ( = 15), or when the total changes in = | for , is extremely small, say, 0.005 , then = . |
