Signal Source Separation Partially Based on Non-Sensor Information

A non-transitory computer-readable medium having computer program instructions stored thereon, wherein the computer program instructions are executable by a computer processor to perform a method, the method comprising:

• (A) receiving at least one sensor response signal;
• (B) receiving at least one source hypothesis signal;
• and
• (C) generating at least one estimated source signal corresponding to the at least one sensor response signal, based on the at least one sensor response signal and the at least one source hypothesis signal.

A method comprising:

• (A) receiving at least one sensor response signal;
• (B) receiving at least one source hypothesis signal;
• and
• (C) generating at least one estimated source signal corresponding to the at least one source hypothesis signal, based on the at least one sensor response signal and the at least one source hypothesis signal.

A method comprising:

• (A) receiving at least one source hypothesis signal;
• (B) receiving at least one initial sensor response signal including a first sensor response signal representing a mixture consisting of components that are coherent with the received source hypothesis signals;
• and
• (C) removing the first sensor response signal from the at least one initial sensor response signal based on the at least one source hypothesis signal, thereby producing a reduced sensor response signal set.
