| 11. A method for processing two or more received primary signals to cancel unwanted coupling onto the two more primary signals
from alien signals, the method comprising:
receiving two or more signals, wherein each of the two or more signals comprise primary components and coupling components;
for a first signal of the two or more signals, performing a decision operation to isolate the primary component;
subtracting the primary component from the first signal to isolate the coupling component;
filtering the coupling component to generate a cancellation signal; and
combining the cancellation signal with second signal of the two or more signals to remove at least a portion of the coupling
component from the second signal.
