The present invention is a method and apparatus for separating a plurality of radio frequency signals, comprising N number of signal collectors, each signal collector receiving the plurality of signals from a location different than the other signal collectors, and N being an integer from 2 to infinity; N number of transmission means, each transmission means conducting the signals received from one signal collector; and, N (N-1) number of signal cancellation means, each signal cancellation means having reference, error input and output lines, the reference line coupled to one transmission means and the error and output lines coupled to another transmission means; the signal cancellation means and transmission means being interconnected so that each transmission means is coupled to the output and error lines of N-1 signal cancellation means and the reference line of N-1 other signal cancellation means, and no signal cancellation means having the same transmission means coupled to their output and reference line; each signal cancellation means substantially nulling in the transmission means couled to its output line a predominant signal appearing in its reference line, thus defining a different predominant signal in the transmission means coupled to the output line of the signal cancellation means; thus, the signal cancellation means substantially null out N-1 signals from each transmission means.
