Abstract
A signal processing system includes a plurality of detectors for detecting signals, each detector receiving signals from plural sources; and a processor for receiving the detected signals and producing a reconstruction filter for filtering the detected signals to produce reconstructed source signals in which each source signal is reconstructed without interference from the other source signals. The reconstruction filter is produced such that cross-polyspectra of the reconstructed signals are forced to approach zero.
