cuOFDM

CUDA for digital communications using the OFDM

This project, cuOFDM, implements an OFDM transmit/receive pipeline in CUDA. Currently, cuOFDM transmits, receives, and applies noise to multiplexed QAM256 symbols. The current pipeline, tested on an NVIDIA GTX 1060 6GB machine, can achieve 100Mbps loopback throughput. cuOFDM is a work in progress - next steps include subcarrier scheduling, cyclic prefixing, and channel coding. Direct integration with common software defined radio (SDR) heads will also be explored.

Build Instructions

The following instructions are for Linux distributions.

1. Navigate to project root
2. mkdir build - Create build directory
3. cd build - Navigate to build directory
4. cmake .. - Run CMake setup
