MUSIC and ESPRIT algorithms are two of the most widely known and used signal source estimation techniques. This study aims at the comparison of the performances of these two techniques. In this study, the signals coming toward uniform linear antenna arrays are estimated using MUSIC and ESPRIT algorithms. Estimation performances of the same related to signal arrival angle are compared with each other. The obtained results show that MUSIC algorithm gives more accurate and definite results for moderately low SNR, whereas ESPRIT algorithm gives accurate results for moderately high SNR. On the other hand, ESPRIT algorithm provides ease of calculation, decrease in capacity and cost.
