==ELECTRONIC DEVICE AND METHOD FOR DIGITAL PREDISTORTION IN WIRELESS COMMUNICATION SYSTEM - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18122755 titled 'ELECTRONIC DEVICE AND METHOD FOR DIGITAL PREDISTORTION IN WIRELESS COMMUNICATION SYSTEM

==Simplified Explanation==

The abstract describes a method performed by an electronic device that involves identifying active units in a digital pre-distortion (DPD) circuit based on the channel bandwidth and resource allocation. The method generates a DPD output signal and an amplifier output signal using the active DPD units, a digital-to-analog converter (DAC), and a power amplifier (PA). While the DPD output signal is generated, other DPD units are deactivated.

* The method identifies active DPD units based on channel bandwidth and resource allocation.
* It generates a DPD output signal using the active DPD units.
* It generates an amplifier output signal using the DPD output signal, a digital-to-analog converter (DAC), and a power amplifier (PA).
* While the DPD output signal is generated, other DPD units are deactivated.

== Potential Applications ==
* This technology can be applied in wireless communication systems, such as cellular networks, to improve signal quality and reduce interference.
* It can be used in satellite communication systems to enhance transmission efficiency and minimize distortion.
* This method can be implemented in radar systems to improve the accuracy and reliability of target detection.

== Problems Solved ==
* The method solves the problem of inefficient resource allocation in DPD circuits by identifying and utilizing only the active DPD units based on the channel bandwidth and resource allocation.
* It addresses the issue of signal distortion by generating a DPD output signal that compensates for nonlinearities in the amplifier.

== Benefits ==
* By deactivating unused DPD units, the method reduces power consumption and improves overall system efficiency.
* The technology enhances signal quality and reduces distortion, leading to improved communication performance.
* It allows for dynamic adaptation to different channel bandwidths and resource allocations, optimizing the DPD circuit's performance in various scenarios.


==Original Abstract Submitted==

According to embodiments, a method performed by an electronic device includes: identifying a channel bandwidth; identifying one or more active DPD units among a plurality of DPD units of a digital pre-distortion (DPD) circuit based on the channel bandwidth and amount of resource allocated within the channel bandwidth; generating a DPD output signal of the DPD circuit based on the one or more active DPD units; generating an amplifier output signal based on the DPD output signal of the DPD circuit, a digital-to-analog converter (DAC), and a power amplifier (PA). While the DPD output signal is generated, at least one DPD unit different from the one or more active DPD units among the plurality of DPD units of the DPD circuit is deactivated.
