Create Realistic 5G Non-Terrestrial Network (NTN) Simulations from PHY to Core

Analyze network KPIs for various geographic, atmospheric environments and satellite network configurations, while augmenting EXata’s statistical models with PathWave System Design high-fidelity modeling.

EXata uses PathWave System Design for simulation of selected Tx-Rx pairs.

  • UE handover across two HAPS-based gNB nodes
  • Antenna tracking and channel estimation algorithm for high mobility
  • Frequency-dependent RF component impairments

EXata provides signaling and traffic in the overall network scenario.

  • Pre-compensation algorithms and beamforming algorithms are used for Tx
  • Includes channel effects such as fading, noise and Doppler based on the mobility and environment specified in the EXata scenario
  • Typical UE Rx processing is performed in PathWave System Design

Array Active Impedance and Load-Pull Modeling

PathWave System Design already simulates active impedance in phased arrays and is correlated against Keysight and 3rd party Finite Element Method (FEM) simulators. Now Keysight is adding X-parameters load pull modeling, enabling engineers to accurately simulate the interaction between the power amplifiers and the array active impedance. PathWave System Design’s unique load-pull simulation creates the most accurate Phased Array Digital Twin, with hardware verified by Keysight instrumentation.
