摘要：
In applications employing phase-shift keying modulation, a phase rotator as disclosed herein is used to rotate the constellation of signal vectors before carrier modulation in order to maximize modulator output power. Such a rotator may be applied in the digital domain (to complex signals having either binary-valued or multi-valued components) or in the analog domain.
