Underdetermined DOA Estimation via Independent Component Analysis and Time-Frequency Masking

<table>Overall mean absolute error in estimated DOAs (in degrees) obtained by the proposed algorithm as a function of the frame length when two microphones are used and three sources are present. The signal length of 4 s was used.</table>
