Principle of vector synthesis predistortion linearizers controlling AM/AM and AM/PM independently

This paper using vector diagram illuminates the operation principle of vector synthesis predistortions and proves they can control amplitude modulation to amplitude modulation (AM/AM) and amplitude modulation to phase modulation (AM/PM) separately. A vector synthesis predistortion linearizer is designed to verify this thought and the results show the correctness of this thought.
