Explain what you observe. Compare both with the LMS and the Wiener solution. Problem II In the class website ( http://cnel.ufl.edu under classes) you will find a time series called speech 1. This file contains a spoken sentence We were away a year ago sampled at 10 KHz, 12 bits A/D. The purpose here is also to compare the quality of RLS predictors in this time series. The difficulty is that speech is nonstationary! Normalize the error power by the input signal power and use this measure to compare the different predictors and windows. I suggest that you use filters of order 6 and 15. Compare with both the LMS and Wiener solution....
