| | 3 | == OFDM Reference Design v13.0 (coming soon) == |
| | 4 | The code and models for this design correspond to [source:/@X svn rev X]. |
| | 5 | [[BR]] |
| | 6 | This project requires the latest versions of the 10.1 release of the Xilinx tools (ISE 10.1.03 + IP2, EDK 10.1.03, Sysgen 10.1.3.1386). |

| | 10 | '''Hardware Changes''' |
| | 11 | * OFDM PHY Changes: |
| | 12 | * Added support for 2x1 Alamouti mode to the PHY |
| | 13 | * Added new [wiki:OFDM/MIMO/Docs/AutoResponse Auto Response] subsystem to the PHY (DATA-ACK turnaround now just 17µs!) |
| | 14 | * Moved pilot tone phase estimator before equalizer so phase correction can be applied earlier |
| | 15 | * Added logic to adjust RSSI value in read-back register to compensate for RF gain choice |
| | 16 | * Shortened coarse CFO estimation window to 64 samples, to avoid corruption when the channel delay spread is non-zero |
| | 17 | * Moved the Tx scaling after the interpolation filters, so filter outputs (not inputs) can be saturated before transmission |
| | 18 | |
| | 19 | '''Software Changes''' |
| | 20 | * WARPMAC/WARPPHY: |
| | 21 | * Updated phyHeader definition to use 16-bit MAC addresses and to include third address (can be used as a relay address, for example) |
| | 22 | * New macros to help configure the PHY's auto response system |
| | 23 | * Updated with new PHY registers and options |
| | 24 | * CSMAMAC: |
| | 25 | * Updated to use PHY's auto response to automatically transmit ACKs |
