中文摘要: 将大规模天线(Massive MIMO)技术应用到认知无线电自组网(CRAHNs)中,可以极大地提高CRAHNs网络的通信容量和可靠性。在基于大规模MIMO的分簇CRAHNs网络(MM-CRAHNs)中,单天线节点(SN)、多天线节点(MN)和大规模天线节点(MM)共存,多种不同类型节点间需要同时进行多业务的通信。混合节点间的通信涉及新场景下的混合天线模型及其信道估计、空频域和发射功率的联合优化、波束形成发送技术和接收技术等。本项目研究MM-CRAHNs网络中混合天线阵的传输组网方案和优化设计:MM-CRAHNs网络中基于混合天线模型的信道估计与导频模式优化设计的研究;MM-CRAHNs网络中空频域和功率的联合优化方案的研究;MM-CRAHNs网络中基于混合天线模型的波束形成发送和接收技术的研究。

英文摘要: The advanced Massive MIMO technique could be introduced in cognitive radio ad hoc network (CRAHNs) to improve the network communication capacity and reliability. Thus, in the clusterd CRAHNs with Massive MIMO (MM-CRHAN), there coexist single-antenna nodes, multiple- antennas nodes and massive-antennas nodes. These hybrid types of nodes support mixed services simultaneously. Communication between different nodes involves works as establishment of new hybrid models, channel estimation, joint allocation of resources such as space, frequency and power, and research of beamforming transceiver techniques. The project focuses on the design and optimization of transmission and networking strategies, the design and optimization of channel estimation and pilot pattern, the joint resource allocation scheme, and the research of beamforming transceiver techniques in MM-CRAHNs with hybrid antenna arrays.
