Federated learning (FL) is a type of distributed machine learning that enables the preservation of clients' data privacy from adversaries and even the central server. To address existing FL limitations such as vulnerability to inference or decreased test accuracy, this paper proposes incorporating federated learning in the inner workings of multiple-input multiple-output (MIMO) systems. The paper focuses on MIMO satellite communication (SatCom), where the receiver is a linear array antenna. Researchers aim to find the channel capacity for low Earth orbiting satellites whose positions are unknown to the terrestrial receiver. In such scenarios, line-of-sight becomes more dominant and path loss reduces. To analyze channel capacity in MIMO systems, researchers typically find eigenvalue distribution for the channel matrix multiplied by its conjugate. When modeled as pure line-of-sight, the channel matrix H becomes a Vandermonde matrix and eigenvalue distribution is unknown; only asymptotic behavior studies have been conducted. This paper approximates average channel capacity and outage probability assuming perfect channel state information (CSI). Simulation results show that only three terms of an infinite summation would give us average capacity with high accuracy. Incorporating federated learning into MIMO systems can provide a unique solution for increasing demand for high-performance next-generation wireless communications while preserving clients' data privacy from adversaries and even central servers.

Federated learning is a way to keep people's data private while still using it to improve technology. It has some problems, like not always being accurate. A group of researchers wrote a paper suggesting using federated learning in a type of communication system called MIMO, which uses antennas. They want to figure out how much information can be sent through satellites that move around a lot. To do this, they use math to look at the signals that go through the antennas. The researchers found that adding federated learning to MIMO systems could help make them better without giving away people's private information.
Definitions
- Federated learning: A method of machine learning where data is kept on individual devices and only shared with other devices for training purposes. - Privacy: Keeping personal information secret or protected. - Vulnerability: Being open to harm or danger. - Inference: Making guesses or predictions based on available information. - Accuracy: How close something is to the truth or correct answer. - Multiple-input multiple-output (MIMO): A communication system that uses multiple antennas for both sending and receiving signals. - Channel capacity: The maximum amount of information that can be transmitted over a communication channel. - Conjugate: A mathematical operation involving complex numbers. - Simulation results: Data obtained from computer models or simulations rather than real-world experiments.
