WIRELESS COMMUNICATION DEVICE AND OPERATING METHOD OF WIRELESS COMMUNICATION DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18449130 titled 'WIRELESS COMMUNICATION DEVICE AND OPERATING METHOD OF WIRELESS COMMUNICATION DEVICE
Simplified Explanation
The abstract describes a wireless communication device with a pre-distortion circuit, power amplifier, measurement circuit, filtering circuit, and pre-distortion coefficient update circuit.
- The pre-distortion circuit generates a pre-distortion signal by pre-distorting an input signal based on a pre-distortion coefficient.
- The power amplifier amplifies the pre-distortion signal to generate an output signal.
- The measurement circuit measures the magnitude of frequency components of adjacent channels in the output signal.
- The filtering circuit includes an error filter that filters the error signal based on the input and output signals.
- The pre-distortion coefficient update circuit updates the pre-distortion coefficient based on the error signal or the filtered error signal.
Potential Applications
- Wireless communication systems
- Mobile devices
- Telecommunications equipment
Problems Solved
- Improving signal quality
- Reducing interference with adjacent channels
- Enhancing overall system performance
Benefits
- Enhanced signal accuracy
- Improved spectral efficiency
- Better overall communication reliability
Original Abstract Submitted
A wireless communication device includes a pre-distortion circuit configured to generate a pre-distortion signal by pre-distorting an input signal based on a pre-distortion coefficient, a power amplifier configured to generate an output signal by amplifying the pre-distortion signal, a measurement circuit configured to measure a magnitude of a first frequency component of a first adjacent channel and a magnitude of a second frequency component of a second adjacent channel of the output signal, a filtering circuit, that includes an error filter, configured to generate a filtered error signal by filtering an error signal that is based on the input signal and the output signal, the error filter is configured based on the magnitude of the first frequency component and the magnitude of the second frequency component, and a pre-distortion coefficient update circuit configured to update the pre-distortion coefficient based on the error signal or the filtered error signal.
