Abstract
This paper mainly proposes an algorithm which can measure the indeterminate phase shift in the measure path and make the final result attain expected accuracy of phase matching. The measure architecture is based on I/Q demodulation, and in the paper, the classical architecture of feedforward amplifier is slightly modified at the error extraction loop and error cancellation loop to get better performance.
