==DETERMINATION OF DIGITAL PRE-DISTORTER SIZE OF AN ACCESS NODE - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240275437 titled 'DETERMINATION OF DIGITAL PRE-DISTORTER SIZE OF AN ACCESS NODE

**Simplified Explanation:**
The patent application describes mechanisms for determining the size of Digital Pre-Distortion (DPD) in an access node operating in a digital massive MIMO system. The access node has multiple antennas, radio chains, and DPDs. The method involves obtaining channel gain estimates for each antenna, determining the size of each DPD based on a utility function dependent on the channel gain estimates, and allocating the coefficients to each DPD.

**Key Features and Innovation:**
- Mechanisms for DPD size determination in an access node in a digital massive MIMO system.
- Utilizes channel gain estimates per antenna to determine the size of each DPD.
- Allocates coefficients to each DPD based on the determined size.

**Potential Applications:**
- Wireless communication systems
- 5G networks
- Telecommunication infrastructure

**Problems Solved:**
- Efficient allocation of resources in a digital massive MIMO system.
- Improved performance of DPDs in access nodes.

**Benefits:**
- Enhanced signal processing capabilities.
- Optimal utilization of resources.
- Improved overall system performance.
