摘要: 当前5G网络信号传输算法较难实现正交化接收,使得传输子信道频率混叠严重,且超密度传输过程中存在节点互干扰的现象。为此,提出一种能够改善频率漂移难题的5G网络信号传输算法。依据传输子信道及小区基站间频率混叠过程中存在的频率漂移特征频率,构建超密度圆环排序结构,将处于超密度状态下的接收节点进行正交化排序,减少信道-信号间频率干涉现象,提高数据传输精确度,基于差分机制设计方位角精度优化方法,降低数据误码率。仿真结果表明,与当前5G领域常用的混沌频率漂移消除优化传输机制、高精度数据传输调节机制相比,该算法具有更高的数据吞吐水平与数据传输质量,且其传输误码率更低。

Abstract: In order to solve the problem as difficult to achieve orthogonalization reception,and the transmission sub channel frequency aliasing serious transmission sub channel frequency aliasing,as well as strong interference between nodes in the process of super density transmission in the current 5G network signal transmission algorithm,a 5G network signal transmission algorithm which can improve the frequency drift problem is proposed in this paper.The super density circular ring sort structure is constructed based on the frequency drift characteristic frequency of the transmission subchannel and the frequency aliasing between the base stations in the cell to orthogonally sort receiving nodes in the superdensity state for reducing the frequency interference between channel-signal,and improving the accuracy of data transmission.The optimization method of azimuth precision is designed based on the difference mechanism and reduce the occurrence of data error rate.Simulation results show that this method has higher data throughput and data transmission quality,and lower transmission error rate compared with the current chaotic frequency drift 5G commonly used in the field of eliminating transmission optimization mechanism high precision adjustment of data transmission mechanism.
