    2121 * Version 4: Posted on November 2008, modified January 2009. The WARPLab MIMO 2x2 and 4x4 Reference Designs have been updated to version 10 of the Xilinx tools. The update required some changes in the Sysgen model resulting in minor changes in the Reference M code. The Capture Offset parameter has been changed to a Transmitter Delay parameter (look at the warplab_defines.m code and the WARPLab examples), the Capture Offset was a receiver parameter, the Transmitter Delay is a transmitter parameter and should be downloaded to the transmitter node. Two bitstreams are provided, one bitstream to program the boards in the 2x2 MIMO configuration and another bitstream to program the boards in the 4x4 MIMO configuration. Reading of RSSI values is supported by the 2x2 MIMO bitstream but not by the 4x4 MIMO bitstream. Continuous transmission mode is supported by both the 2x2 and 4x4 bitstreams. When the boards are programmed with the 4x4 MIMO bitstream 2x2 MIMO communication is possible but reading of RSSI values is not possible. The MATLAB Reference functions support both 2x2 and 4x4 MIMO bitstreams.

    23  * Version 5: Posted on September 2009. The WARPLab MIMO 2x2 and 4x4 Reference Designs have been updated to include Automatic Gain Control (AGC). Previous versions of WARPLab required Manual Gain Control (MGC), the user was required to set receiver gains manually. In this new Version 5 release the user can choose between AGC or MGC mode using simple m-code functions. Two bitstreams are provided, one bitstream to program the boards in the 2x2 MIMO configuration and another bitstream to program the boards in the 4x4 MIMO configuration. AGC and MGC are supported by both bitstreams. Reading of RSSI values is supported by the 2x2 MIMO bitstream but not by the 4x4 MIMO bitstream. Continuous transmission mode is supported by both the 2x2 and 4x4 bitstreams. When the boards are programmed with the 4x4 MIMO bitstream 2x2 MIMO communication is possible but reading of RSSI values is not possible. The MATLAB Reference functions support both 2x2 and 4x4 MIMO bitstreams.
