“…To still get acceptable results, the DOA estimator has to be as good as possible. There are many papers covering DOA algorithms using a huge amount of antennas, samples per antenna or a high SNR, respectively (Ottersten et al, 1992;Li et al, 1998;Xin and Sano, 2004;Viberg et al, 1991b;Lopes et al, 2003;Stoica and Sharman, 1990b;Gershman and Stoica, 1999), to make use of statistical asymptotic analysis. Yet, there are few papers which deal with the single snapshot case.…”
