摘要: Various digital pre-distortion systems for use in transmitters are disclosed. The system comprises an observing path, which performs either undersampling or radio frequency sampling of the output a power amplifier. Undersampling may be performed at rate, causes aliasing to occur undersampled domain. Both and reduces complexity by removing any down mixing modules anti-aliasing modules, while maintaining reasonable performance systems.
