Abstract: We take into account multiple-input– multiple-output (MIMO) two-way relaying channels wherever a try of multi antenna users needs to exchange data with the assistance of a non-generative multi antenna relay. A low-complexity joint beam forming and power management theme is projected. The projected beam formers 1st align the channel matrices of the user try then decompose the aligned channel into parallel sub channels. 2 power management problems, i.e., power allocation and power management, addressed sum-rate optimizing power allocation is projected to assign power between all sub channels and nodes. Second, quality of service (QoS) satisfying power management is projected to reduce the whole transmission power within the network. Simulation results justify that the projected joint beam forming and power management theme delivers higher sum-rate performance or consumes lower transmission power next with existing schemes.
