= 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 [source:/ 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.

The most recent version of the OFDM Reference Design is v18.0. See the [wiki:OFDMReferenceDesign/Changelog release history] for the design files and release notes.

== 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.)
