基于自由空间光通信的云无线接入网上行链路优化研究

Optimization of Uplink of Cloud Radio Access NetworksBased on Free Space Optical Communication

为了提高云无线接入网的前传传输速率,探讨了将无线电自由空间光应用于云无线电接入网的网络优化中,设计了上行链路中联合射频和无线电自由空间光链路的前传,使用户的传输速率最大化。仿真实验表明,添加无线电自由空间光链路大大提高了用户的速率。

In order to improve the transmission rate of fronthaul of cloud radio access network, this paper discusses the application of radio free space optical in the network optimization of cloud radio access network, and designs the combined radio frequency and radio free space optical link in uplink to maximize the transmission rate of users. Simulation results show that adding radio free space optical link can greatly improve the transmission rate of users.
