Study of Sensor Spacing and Number in Blind Source Separation

In blind source separation, high frequency range needs a narrow sensor spacing and low frequency range needs a wide sensor spacing. The traditional methods adopt a fixed sensor spacing to separate the mixtures, so they can't get a good result. The analysis shows that the number and spacing of the sensors can effect the result of blind source separation. This paper presents a method using several separating subsystems. With this method we can get a better result.
