Research of Adaptive Canceller Based on Reverberation Correlation of the Beams

The purpose of this paper is to detect the echo under reverberation background by using adaptive interference cancellation. And in this paper, experimental data was treated. Reference signal is separately one single beam or symmetrical double beams in the processing of adaptive reverberation cancel. As the results shown, it is clear that the reverberation is made a great degree of inhibition after adaptive reverberation cancellation treatment. And when symmetrical double beams are as the reference signals, the effect is obviously better than one single beam.
