中文摘要：
针对多跳多中继无线网络中的协作波束形成技术进行研究。在基于放大转发机制的三跳协作通信系统中,对2个中继节点簇的协作波束形成矢量进行联合设计,以求在目标节点获得最大的接收信噪比。该方法首先将原始优化问题加以推导简化,然后应用半定规划方法求解获得协作波束形成矢量的次优解,并结合对分搜索算法加以改进。仿真结果表明,提出的协作波束形成方法可取得明显优于固定放大增益中继策略的接收信噪比。
英文摘要：
A cooperative beamforming solution for the multi-hop multi-relay wireless networks was propsed. In such networks was proposed, the communication between source and destination was accomplished by a three-hop channel with aid of two relay clusters under amply-and-forward （AF） protocol. In order to maximize the receive signal-noise ratio at destination, the proposed method first formulated the original optimization problem, then a suboptimal solution could be obtained by semidefinite programming （SDP）. An improved solution was also proposed in combination with bisection search. Finally, the effectiveness of proposed method is verified through computer simulations.
