OFDM Reference Design v09 (2008-Jun-11)
- Download the XPS project: OFDM_ReferenceDesign_v09.zip
- Built using cores and code as of repository revision 906
- This version assumes a different location for TxDCO calibration information in the EEPROM of the radios. Please re-calibrate before running (instructions are here)
- This will be the last reference design that will use the version 9 Xilinx tools. Reference Design v10 will use the version 10 Xilinx tools.
- Updated warpmac/warpphy & csmamac
- Header interrupts are used to pipeline receive processions (i.e. an ACK is constructed and loaded into a PHY before the packet is even completely received)
- Rx Data to Tx ACK turn-around time reduced from 80 microseconds to 30 microseconds
- By default, left and right push buttons use left and right radios respectively (only for MIMO WARP kits)
- Numerous tweaks to MAC timing parameters
OFDM Reference Design v08 (2008-Feb-08)
- Download the XPS project: OFDM_ReferenceDesign_v08.zip
- Built using cores and code as of repository revision 834
- Updated OFDM PHY
- Added support for header-only packets (like ACKs); numFullRateSymbols can be zero
- Last two bytes of header are now a 16-bit CRC of just the header
- Added new interrupt output for good header; asserts for non-header-only packets when header CRC passes
- Added TxDone interrupt output; asserts when a packet transmission finishes
- Fixed bugs in dynamic modulation mask usage
- Updated warpmac/warpphy & csmamac
- Changes to support new PHY features
- Added TxDone & GoodHeader interrupt handlers; unused in this version
- Added lots of comments to the source code to better explain various MAC/PHY interactions
