... clear that though the exact inverse filtering outperforms the matched filter under clean conditions, it performs significantly poorer when there are interfering noise sources. This can be attributed ... even in the presence of modest interference. When a Gaussian noise source at 15 dB signal-to-competing noise ratio levels was introduced at (3.0,5.0,1.0)m, the performance on the output of the ex...
