 In cooperative systems, the relay helps a direct source-destination link. Cooperative communication with multi-antenna relays can significantly increase the reliability and speed. However, cooperative MIMO detection would impose considerable complexity overhead onto the relay if a full detect-and-forward (FDF) strategy is employed. In order to address this challenge, we propose a novel cooperative partial detection (CPD) strategy to partition the detection task between the relay and the destination. CPD utilizes the inherent structure of the tree-based sphere detectors, and modifies the tree traversal so that instead of visiting all the levels of the tree, only a subset of the levels, thus a subset of the transmitted streams, are visited. Based on this methodology, the destination combines the source signal and the partial relay signal to perform the detection step.

 Using the WARPLab platform, we show that with the CPD approach, the relay can avoid the considerable overhead of MIMO detection while helping the source-destination link to improve its performance.

 In this setup, multiple WARP boards are connected to a host PC  through an Ethernet switch. A set of boards are designated as the transmitters and a set of boards are designated as the receivers through the WARPLab framework. To transmit, raw samples (I/Q) values are generated in MATLAB and uploaded to the transmit boards via Ethernet. When the host PC sends a trigger signal to all nodes via Ethernet, the transmit boards modulate the raw samples
