ANALOG PREDISTORTER CORE MODULE AND ANALOG PREDISTORTER SYSTEM

Document Type and Number:

WIPO Patent Application WO/2016/074218

Kind Code:

A1

Abstract:

Disclosed are an APD core module and an APD system, which belong to the field of communications. The APD core module comprises: a radio-frequency delay module, an envelope module and a contact matrix module, wherein the radio-frequency delay module is used for receiving a feed-forward radio-frequency signal, generating multiple paths of radio-frequency delay signals with different delays according to the feed-forward radio-frequency signal, and outputting each path of the radio-frequency delay signals to the contact matrix module; the envelope module is used for receiving the feed-forward radio-frequency signal, performing an envelope detection on the feed-forward radio-frequency signal to obtain multiple paths of envelope signals with different delays, and outputting each path of the envelope signals to the contact matrix module; and the contact matrix module is used for receiving each path of the radio-frequency delay signals, each path of the envelope signals and a predistortion coefficient from outside, and generating a predistortion signal according to the predistortion coefficient, each path of the radio-frequency delay signals and each path of the envelope signals. The present invention can effectively offset the distortion generated by a PA.
