METHOD AND APPARATUS FOR ROTATING PHASE OF COMPLEX PSK SIGNAL

摘要

PROBLEM TO BE SOLVED: To provide a method and apparatus for rotating a phase of a complex PSK signal.SOLUTION: A phase rotator 200 receives two input signals 310A and 310B, which are real-valued components of a complex input signal. Adders 210A and 210B are arranged such that one real component 320A of a complex output signal is the difference between the input signal components 310A and 310B, and another real component 320B of the complex output signal is the sum of the signals 310A and 310B.
