Realtime OFDM with CUDA Acceleration, SIMD, and Rust

This repository holds the code and whitepaper for my final Principles of Wireless project at Olin College of Engineering. This project implements a full, realtime, OFDM datalink between an Ettus B210 SDR receiver and transmitter.

The final algorithms and code presented in this repository implement a communication system capable of XXX gb/s communication with an error rate of xxxx. The final channel features these techniques:

• 64QAM
• Frequency Correction with Shmidl-Cox algorithm
• Phase Offset Correction
• Guardbands
• Error Correction with Hamming Codes

The "video" demo features an application using gstreamer to send and receive data through the channel, as a proof of concept of live video streaming.

To make it easier for fellow and future classmates, I've taken the liberty of bundling .exe/.deb/.app for Windows/Linux/Mac. This should make it easier to send and receive data without the need to formally install UHD.

Throughout the semester, we learned about wireless modulation and demodulation techniques, culminating in a final "mega" lab where we transmitted and received OFDM data with the Ettus B210 USRP.
