Abstract: Performance of MUSIC and maximum likelihood direction-of-arrival estimation in the "threshold" region is compared with the performance of the recently introduced G-MUSIC, based on the general statistical analysis (GSA) methodology. While the superiority of G-MUSIC over MUSIC has been demonstrated, it remains to be established whether G-MUSIC also outperforms MLE in scenarios within the threshold region. Comparisons of likelihood functions for MUSIC and G-MUSIC generated solutions as well as clairvoyantly optimized solutions are conducted to address this question.
