 Figure below shows our 2 x 2 three node cooperative system setup. The three WARP boards are connected to a PC through Ethernet. In order to emulate channel behavior, an Azimuth ACE 400 WB wireless channel emulator is used. The emulator can support a range of channel models, including the TGn models as well as a subset of winner channel models. Moreover, custom channel models can be defined and emulated using the emulator's software interface.

 The parameters of the Azimuth channel emulator can be controlled through Azimuth Director software. The figure below shows one screenshot of the node topology in this software used for the cooperative partial detection setup. Port B corresponds to the source transmitter in the first time slot. Also, A1 and A4 correspond to the relay two receive antennas in the first time slot, and A2 and A3 correspond to the destination receive antenna in the first time slot. In the second time slot, A2 and A3 are the relay transmit antennas and port B serves as the destination receiver:

 The input transmit power of the WARP radio boards is set to 40 in the coop_setup.m file, and the input power of the emulator ports are accordingly fixed using the WARPLab continuous transmission mode. The path loss factors can, then, be computed as described in the earlier chapters using the following formulae:

 Figure below represents one particular representations, where the power losses on different paths correspond to P_{loss, SR} = 17dB, P_{loss, SD} = 33dB and P_{loss, RD} = 28dB.
