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.

A signal processing system for separating signals received from plural sources via an unknown channel, comprising:
- a plurality of detectors each for detecting said signals received from said 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;
- characterized in producing the reconstruction filter such that higher-order cross-polyspectra of the reconstructed signals are forced to approach zero.
