本文首先分析了TD-SCDMA网络的同频干扰问题,介绍了N频点技术、TFFR算法和动态资源分配技术解决同频干扰的原理和优、缺点,认为N频点技术结合动态资源分配很好地结合了频率和时隙资源的多维分配,通过合理调整资源来降低同频干扰,取得了较好的效果。
This paper first analyzes the co-channel interference problem of TD-SCDMA network, introduces the principle and advantages and disadvantages of N-frequency point technique, TFFR algorithm and dynamic resource allocation technique to solve co-channel interference, and considers that N-point technique combined with dynamic resource allocation is very good Combines the multi-dimensional distribution of frequency and time slot resources, and reduces the co-channel interference by reasonably adjusting resources, and achieves good results.
