IQ MODULATOR, AND ASSOCIATED METHOD

摘要

An IQ modulator (12), and an associated method, for a digital transmitter (10). The IQ modulator forms I- (28) and Q- (32) components which modulate a carrier. The IQ modulator permits simple and quick introduction of frequency offsets (424, 426) to overcome the effects of Doppler shifting (358, 358') or to form channel offsets in an FDMA communication scheme.
