This document discusses spectrum estimation methods and their real-time implementation on TI DSPs. It introduces the autoregressive (AR) model and three estimation methods - periodogram, Burg, and M-covariance. It describes simulating these methods and comparing the estimated spectra to the true spectrum. It then discusses implementing the methods on a DSK6713 in real-time using separate model files for each method. A GUI is created using MATLAB to control the real-time model, enable reloading methods, and visualize the estimated spectra.
