(a) Raw signal on masked area. (b) Dictionary coded signal overlaid on true signal area. (c) Maximum windowed signal overlaid on true signal area. (d) Correlation windowed signal overlaid on true signal area. White arrows denote reverberant echoes, and red arrows denote true signals of smaller amplitude. As shown in the zoomed insets, the signals of smaller amplitude are retained in the correlation-windowed signal (d), compared to (c).
