WARP OFDM Reference Design
The WARP OFDM Reference Design implements a real-time network stack on a WARP node. The design includes a MIMO OFDM physical layer and flexible MAC interface for building custom protocols. This design demonstrates the full MAC/PHY capabilities of WARP. All processing (hardware control, signal processing, MAC protocol) is executed in real-time by each WARP node. PCs can be attached to WARP nodes via Ethernet, but are used only for traffic generation/analysis.
This design draws from many parts of the WARP repository. Each release integrates known-good, interoperable versions of each component. All of the MAC and PHY components are open-source and are available in the repository.
We have built a number of applications on top of the OFDM Reference Design. A few basic applications are included with the reference design project to help get started with custom research applications.

Reference Design Structure
The design consists of the following components:
- MAC Application: top-level C code implementing a wireless MAC protocol.
- WARPMAC framework: Low-level PHY control and MAC primitives, implemented in C code
- OFDM PHY: FPGA implementation of the OFDM physical layer, built in System Generator
- Support Peripherals: Other peripheral cores in the FPGA (timer, radio bridges, etc.)
