SEA V2X Add-On for LabVIEW -

Simulate Doppler shift, fading and multipath effects for RF


Part Number: 66000054

The package is designed to simulate Doppler shift, fading and multipath effects for RF


  • RF channel emulation (8-tap) covering V2X standard emulation scenarios
  • Combinable with V2X communication protocols
  • Full LabVIEW API for emulation parameter control
  • Interactive control interface
  • Applicable to NI software defined radios (USRP or VST Gen.1)

This software add-on provides the capability to combine all the effects of a signal on 8 different propagation paths (8-tap) in real-time as standalone or in combination with SEA V2X communication add-ons based on NI software defined radios.

RF-transmissions are distorted by real world effects altering the wave fronts. These distortions seriously affect the quality and performance of wireless information transmission, especially in traffic oriented RF-applications like V2X.
The emulation of these effects is required to test and validate the robustness of receiver setups and chip sets.

Typical major physical propagation effects are

  • attenuation
  • fading by atmospheric effects
  • Doppler (frequency) shift by relative motion of transmitter and receiver
  • multipath effects resulting from the wavefront being reflected on objects along the propagation path

The toolkit represents the distorted RF-wavefront of one transmitter (typically vehicle or other traffic object) at the antenna of a receiver. All emulation parameters can be changed actively by a comfortable LabVIEW API. 

Parameter sets defined by standardization bodies, e.g. ETSI can be simulated with the CEM toolkit.

This toolkit is also available as standalone package or as an integrated component of  S.E.A. V2X turnkey test systems for functional testing, RF-behavior measurements and customer specific automated test systems.
