The following graph, produced with the Matlab script plot_benchmark_heat2d. Given the current estimate x ˆ [n | n], the time update predicts the state value at the next sample n + 1 (one-step-ahead predictor). Estimation of DOA is performed from one of these subspaces, assuming that noise in each. Image deblurring (or restoration) is an old problem in image processing, but it continues to attract the attention of researchers and practitioners alike. I guess it's easier to use an analogy to understand the problem. Alternatively you can use Octave which is a very good open source alternative to MATLAB. an interactive introduction to MATLAB MATLAB, and no previous programming experience. Most traditional DOA estimation methods focus on narrow-band sources. This estimation technique based on maximum likelihood of a parameter is called Maximum Likelihood Estimation or MLE.
