HIGH ORDER DIGITAL POST-DISTORTION PROCEDURES - A simplified explanation of the abstract
This abstract first appeared for US patent application 17526821 titled 'HIGH ORDER DIGITAL POST-DISTORTION PROCEDURES
Simplified Explanation
Methods, systems, and devices for wireless communications are described in this patent application. The invention focuses on improving power amplifier (PA) non-linearity models and non-linear equalizer functions in base stations and user equipment (UE). Here are the key points:
- The base station notifies the UE when it changes the PA non-linearity model.
- The base station transmits a set of parameters for the PA model and a set of parameters for a non-linear equalizer function for the UE to use during a digital post-processing procedure (DPoD).
- The base station can indicate a lookup table, a vector of lookup tables, a set of kernels, or both kernels and coefficients for the PA model to the UE.
- Similarly, for the non-linear equalizer function, the base station can indicate an explicit indication of the function, a lookup table, or a series of kernels with or without corresponding coefficients.
Potential applications of this technology:
- Wireless communication systems
- Mobile networks
- Internet of Things (IoT) devices
- 5G and future generations of wireless networks
Problems solved by this technology:
- Improving power amplifier non-linearity models
- Enhancing non-linear equalizer functions
- Optimizing wireless communication performance
- Reducing signal distortion and interference
Benefits of this technology:
- Improved signal quality and reliability
- Enhanced data transmission rates
- Better overall performance of wireless networks
- Increased efficiency of power amplifiers
- Enhanced user experience in wireless communication
Original Abstract Submitted
Methods, systems, and devices for wireless communications are described. Generally, a base station may indicate, to a user equipment (UE), when it changes a power amplifier (PA) non-linearity model. The base station may transmit a set of parameters for the PA model, and a set of parameters for a non-linear equalizer function for the UE to use during a digital post-processing procedure (DPoD). The base station may indicate, to the UE, a lookup table, a vector of lookup tales, a set of kernels (e.g., from which the UE may estimate the coefficients of the PA model), or a set of both the kernels and the coefficients for the PA model. Similarly, for the non-linear equalizer function, the base station may indicate an explicit indication of the function, or may indicate a lookup table, or a kernels series (e.g., with or without corresponding coefficients).
