摘要
针对“移动通信”中4G网络中的同频干扰问题,采用单频网络技术方案,主要方法是采用华为SFN软件进行仿真,在软件中将不同位置的同频网络合并为同一虚拟物理小区.用仪表进行实际测试发现,实际物理小区之间的交叠区域的信号干扰比和下载速度得到明显提高,用户的使用感受得到显著提升.单频网络技术对于容量要求不高的城郊、乡村和边远地区的同频干扰问题具有良好的解决能力.
In view of the problem of the same frequency interference in the 4G network of the“mobile communication”course,the author leads the students to adopt the single frequency network technology scheme.The main method is to use Huawei SFN software to simulate and merge the same frequency network in different locations into the same virtual physical cell.In the cell,the overlap area interference between the actual physical cells is significantly reduced,and the network speed is obviously improved,which improves the user’s experience.The actual test with the meter shows that the single frequency network technology has a good ability to solve the same frequency interference.
