Beamforming for NTN Systems with MATLAB

Overview

Non-terrestrial networks (NTNs), particularly with low earth orbit (LEO) and medium earth orbit (MEO) satellites, are central to 5G-Advanced and 6G.  Long links, time-varying geometry, and the need to reduce interference make beamforming essential.  Engineers must co-design antenna arrays, RF front ends, and signal processing while modeling orbital dynamics and propagation.

In this webinar, we present practical RF and system-level techniques for NTN MIMO transceivers to boost performance and avoid costly re-spins.  For transmitters, you’ll learn how to design large phased array beamformers to maximize signal power in an intended direction.  You’ll also learn how to account for beam squinting and phase quantization for those arrays, and nonlinear power amplifiers.  You will see how to model atmospheric losses for these links.  For receivers, you will see how A/D quantization can affect system performance.  We will then relate these signal-level metrics into a throughput estimate.

Highlights

• Orbit propagation modeling, and Doppler generation
• Design and simulation of 5G NTN transceivers
• Integration of antenna arrays and RF front ends
• Link throughput predictions based on waveform-level processing
