英文摘要： Multi-input multi-output(MIMO) has become a mainstream technology in new generation wireless mobile communication system, however, there are still lots of theoretical problems to be studied. In this project, we propose the transmission mechanism and collaborative approach in reconfigurable MIMO system with multi-antenna terminals, expand single-antenna terminals cooperative diversity and distributed MIMO scheme to multi-antenna terminals cooperative MIMO which is more practical in the future and solve system performance constraints in MIMO spatial channel. We create multi-antenna terminals cooperative wireless model with ad-hoc cellular structure wireless channel model, and demonstrate the feasibility of the model according to theoretical analysis and simulation; propose the new idea of dynamic reconfigurable collaborative MIMO, and prove its possibility and the necessity of collaboration from the aspect of mathematics and physics; study the transmission mechanism and collaborative approach with reasonable complexity in multi-antenna terminals cooperative MIMO, and verify the effectiveness of the proposed program by theoretical analysis and computer simulation; put forward the scheme of multi-user cross-layer and resources optimal allocation to improve wireless transmission efficiency of users and system simultaneously. The goal of the research is to exploit the advantage of space dimension resources, further improve the system capacity and provide a valuable reference program for the developing of China's new generation broadband wireless mobile communication network.
