摘要云无线接入数字单元能集中处理、控制与实时联合调度管理基站服务区内用户的信号、消除基站服务区的内部干扰、减少无线设备的使用、降低了无线接入网络的服务成本。本文将大规模天线空间调制技术应用到云无线接入网络中，提出了云无线接入网络中的大规模天线空间调制系统，在系统输入信息离散、均匀分布时推导了系统的互信息，进行了系统的仿真实验。实验结果表明：云无线接入网络中的大规模天线空间调制系统的误比特率和互信息与现有的云无线接入网络中的 MIMO系统相比，性能增益有较大的提高。

Abstract：The users’signals in the service base station can be processed intensively, controlled and real-time managed jointly by cloud wireless with units access which can eliminate the internal interference inside the base station service area, and decrease the number of the wireless devices and the cost of the wireless access network. In this paper, the large scale antenna spatial modulation technology is applied to the Cloud Radio Access Network. The mutual information of the system is deduced when the input information of the system is discrete and uniformly distributed. The system simulation experiment is carried out. Results show that the performance gain of the BER and mutual information of large scale antenna spatial modulation systems in Cloud Radio Access Network are much higher than that existing in MIMO systems in cloud wireless access networks

Key words： Cloud Radio Access Network spatial modulation mutual information BER
