Claim:
1. A method for an arbitrary phase detector to detect and remove an arbitrary phase difference between a sum channel signal and a difference channel signal, the method comprising: an act of the arbitrary phase detector receiving a sum channel signal from a sum channel signal source; an act of the arbitrary phase detector receiving a difference channel signal from a difference channel signal source; an act of the arbitrary phase detector shifting the difference channel signal according to a plurality of potential phase difference pairs φ an act of the arbitrary phase detector correlating the plurality of difference channel signals each having a different phase with the sum channel signal to generate a plurality of sum+difference signals and sum−difference signals; an act of the arbitrary phase detector determining, based on the plurality of sum+difference signals and sum−difference signals, a maximum correlation magnitude difference between the φ an act of the arbitrary phase detector using the maximum correlation magnitude differences between the φ
