针对由于通信干扰严重导致的蜂窝网络数据传输效率不高、能耗较大的问题,提出一种联合QoS约束及波束形成准则的蜂窝网络高效协作传输技术。该技术采用了由宏蜂窝、飞蜂窝组成的蜂窝网络系统模型,分析了网络通信过程中的信号干扰及功率情况。基于QoS约束的高效协作传输算法,采用QoS约束把数据传输的能量效率问题优化成波束成形和功率分配问题,并将Qos约束考虑进波束形成准则,从而改善网络的干扰状态,提高能量效率。实验仿真结果的对比情况表明,该技术可以提高蜂窝网络进行数据传输的能量效率,并减少通信干扰。

Efficient Cellular Networks Collaboration Transmission Technology with QoS Constraints and Beamforming Criterion

For the issues that data transfer efficiency is not high and the energy is larger caused by the serious cellular network interference,a efficient cellular networks collaboration transmission technology with QoS constraints and beamforming criterion was proposed.The technology uses a heterogeneous system model composed of the macrocell cellular network and the femtocell, and analyzes the network communication and power signal interference conditions.Based on QoS constrain efficient collaboration transmission algorithm,the QoS constraints is used to optimize energy efficiency of data transmission into a beam-forming and power allocation,and the QoS constraints is introduced into beamforming criteria to improve the state of the network interference and increase the energy efficiency.The comparison of the experimental results indicates that this technique can improve the energy efficiency of the cellular network for data transmission,and reduce the communication interference.
