THz Wireless Channel Simulation - Advanced Simulation Techniques

How-To Videos

Keysight introduces a new Terahertz (THz) wireless channel module supporting RF frequencies up to 1 THz for free-space optical and wireless communication system simulation. This demo showcases RF propagation of a 16-QAM modulated signal over a 1 km free-space link at 270 GHz, with full support for weather-dependent attenuation including rain, fog, clouds, and atmospheric gases, modeled according to ITU recommendations.

  • THz wireless channel model overview (up to 1 THz)
  • 16-QAM coherent transmitter/receiver for RF
  • Rain attenuation vs. frequency sweep
  • SER vs. frequency and rain rate analysis
  • Eye diagram and constellation diagram analysis
