Environment Simulation

Propagation delay, path loss, Doppler and interference — computed from the geometry of your scene.

What it does

Real channels, from real geometry.

Place transmitters and receivers at arbitrary positions in 2D or 3D, standing still or moving. Sigtera derives the channel from the scene — no hand-tuned delays, gains or frequency shifts.

  • ✓ Propagation delay from distance and speed
  • ✓ Path-loss attenuation by exponent
  • ✓ Doppler shift from platform motion, tracked as the geometry changes
  • ✓ Per-receiver front-end impairments — carrier and clock offset, phase noise, IQ imbalance, DC bias
  • ✓ Self-interference cancellation per platform
  • ✓ Each receiver outputs all transmissions, mixed and time-aligned
How to use it

Build a scene, generate a recording.

  1. 1
    Place platforms

    Add platforms at positions in space, give any of them a velocity to put it in motion, and set the propagation speed and path-loss exponent for the environment.

  2. 2
    Add transmitters

    Give each transmitting platform one or more signals, with start times relative to the scene.

  3. 3
    Add receivers

    Set each receiver's sample rate, noise floor and front-end impairments; optionally cancel its own platform's transmissions.

  4. 4
    Generate

    Each receiver produces a file with every transmission delayed, attenuated, Doppler-shifted, mixed, and time-aligned.
