nvlabs/sionna — reverse-engineered prompt

I want a Python library for communication systems research called Sionna. It should be something a researcher can install with pip and then use from Python or Jupyter notebooks to model wireless and optical communication systems.

The main pieces should cover radio propagation ray tracing, link level simulation, and system level simulation, with GPU support when available. Please make it feel usable for experimentation, with tutorial notebooks, a few runnable examples, tests, and local docs so someone can learn it without digging through the code. It should also be possible to install just the core library without the ray tracing part, or install the ray tracing piece on its own.

Please wire up the repo so it can be installed from source, tested, and the docs can be built and served locally. If there are external setup details for the ray tracing backend or GPU support, just document them clearly and look up the current docs online if you need to.
