SIGNAL PROFILE BASED DATA CAPTURE FOR DIGITAL PRE-DISTORTION CORRECTION

A circuit includes a capture subsystem and digital pre-distortion (DPD) circuitry. The capture subsystem is configured to capture a set of signal samples responsive to a capture enable signal. The DPD circuitry is configured to generate a signal statistics signal based on an input signal, generate a...

Zusammenfassung:	A circuit includes a capture subsystem and digital pre-distortion (DPD) circuitry. The capture subsystem is configured to capture a set of signal samples responsive to a capture enable signal. The DPD circuitry is configured to generate a signal statistics signal based on an input signal, generate a set of DPD coefficients based on the set of signal samples, and apply DPD correction to the input signal to produce an output signal based on the signal statistics signal and the set of DPD coefficients. The set of signal samples includes samples of the signal statistics signal.
