| Abstract: | This article investigates three kinds of source number estimation algorithm(SNEA) based on information theoretic criteria and another SNEA based on Gerschgorin Disks theory and analyzes and compares their performance based on numerical simulation results.It is found that the algorithms based on information theoretic criteria are suitable for the case of white Gaussian noise and Gerschgorin Disks algorithm is suitable for both cases of white noise and colored noise. |
