Python for wireless course will use the opensource framework package called Sionna for rapid implementations of wireless digital communication method and systems.

The Sionna Framwork:

Sionna™ is a TensorFlow-based open-source library for simulating the physical layer of wireless and optical communication systems. The rapid prototyping of complex communication system architectures is as simple as connecting the desired building blocks, which are provided as Keras layers. Using differentiable layers, gradients can be backpropagated through an entire system, which is the key enabler for system optimization and machine learning, especially the integration of neural networks. NVIDIA GPU acceleration provides orders-of-magnitude faster simulation, enabling the interactive exploration of such systems, for example, in Jupyter notebooks that can be run on cloud services such as Google Colab. If no GPU is available, Sionna will run on the CPU.

Sionna is developed, continuously extended, and used by NVIDIA to drive 5G and 6G research. It supports MU-MIMO (multi-user multiple-input multiple-output) link-level simulation setups with 5G-compliant codes including low-density parity check (LDPC) and Polar en-/decoders, the 3GPP channel models, OFDM (orthogonal frequency-division multiplexing), channel estimation, equalization, and soft-demapping. Many other components such as convolutional and Turbo codes, the split-step Fourier method for the simulation of fiber-optical channels, as well as filters and windows for the investigation of single-carrier waveforms are available. Every building block is an independent module that can be easily tested, understood, and modified according to your needs. The documentation is complete and includes references.

The Sionna Advantages:
Most researchers in communications need a tool for link-level simulation to quickly prototype their ideas and benchmark their algorithms against the state-of-the-art. However, apart from proprietary software, there existed no widely-used common open-source tool. Moreover, experts in one domain, say channel estimation, do not necessarily have the time or background to evaluate their algorithm for end-to-end performance, for example, coded bit error rate (BER) over a realistic channel model.

Sionna provides a high-level application programming interface (API) to rapidly model complex communication systems from end-to-end while allowing you to adapt the part(s) your research is about. This enables you to focus on your research while making it more impactful and easily reproducible by others.

Thanks to Keras and TensorFlow, Sionna has native NVIDIA GPU support which makes it super fast and perfectly suited for machine learning research in communications. Sionna was discussed in detail in the 30th episode of the Wireless Future Podcast.

================= Python for wireless communications ==================

Python is in general becoming an extremely popular programming language that can be used for a wide range of applications, including wireless communications. There are several libraries and tools available in Python that can be used to build wireless communication systems, such as:

1. Scapy: A packet manipulation tool that can be used to send, receive, and manipulate wireless packets.
2. PyWireless: A library that provides a set of tools for working with wireless communications, including support for Bluetooth, Zigbee, and more.
3. GNURadio: A toolkit for building software-defined radio (SDR) systems, which can be used to receive and transmit wireless signals.
4. PyLora: A library for working with the LoRa wireless communication protocol, which is commonly used for low-power, long-range wireless communication.
5. PySDR: A library for working with SDRs in Python, including support for various wireless communication standards such as GSM, LTE, and more.
6. Sionna: A TensorFlow-based open-source library for simulating the physical layer of wireless and optical communication systems. The rapid prototyping of complex communication system architectures is as simple as connecting the desired building blocks, which are provided as Keras layers.

These are just a few examples of the tools and libraries available in Python for working with wireless communications. You can find more information and resources online to help you get started with using Python for your wireless communication projects.
