摘要: Methods and systems to reduce clock spurs produced by a direct-RF modular acceptable levels using digital predistortion compensation signal. The signal may be used generate sine wave in the domain with adjustable phase amplitude. added processor (DSP) section of an upconvertor, combined undesired spur it or even cancel out completely. In some implementations, have similar level such that when spur, results having reduced
