Abstract :
Multiple-input-multiple-output (MIMO) technology could bring significant performance enhancement in wireless relay networks, and linear processing at relay terminals obtains greater performance, such as network capacity or MSE performance. An MIMO relay scheme with Quality of Service (QoS) requirements is proposed in this paper, according to the designed networks model, the approximate expression of the capacity of MIMO relay network is derived in detail. Simulation results show that, with a certain signal-to-noise ratio (SNR) constraints, network achievable capacity could be improved obviously with the increasing of relays, while the proposed scheme could also attain ideal capacity performance gain in low SNR regions.
