Satellite Channel Emulation

IZT develops Channel Emulators to simulate the transmission from ground station to the receivers for satellite and terrestrial applications.  Frequently requested channel impairment effects include:

  • Doppler effect (delay and frequency changes over time)
  • Ionosphere and interference simulation in the uplink
  • MUX filtering effects
  • Phase noise simulation
  • Non linearities in payload
  • Multipath fading
  • Thermal noise generation in the downlink

IZT’s Channel Emulators combine exceptional RF performance with modern digital signal processing. Customers confirm that measurement results in the laboratory are reproduced over the transmission link once the satellites had been launched to space.
