Comparing accuracy for ML, MUSIC, ROOT-MUSIC and spatially smoothed algorithms for 2 users

In this article we simulate four famous algorithms in DOA and then compare the algorithms based on their finding and estimating of the accuracy level angels from two different users, having demonstrated the result of simulation of the four algorithms in comparison tables, it is observed that ROOT-MUSIC algorithm have high level of accuracy in estimation of close angles(28, 30 degrees). MUSIC, Spatially Smoothed and ML algorithms have the next steps in accuracy respectively.
