基于频率优化的无线网络互调干扰抑制算法

摘要

The mechanism of the fifth-order inter-modulation was discussed,and a frequency optimization algorithm for reducing the network inter-modulation interference was proposed.The inter-modulation interference produced by frequency combination can be suppressed when the TCH frequencies combination of the cell meets the following requirement:935 ×106 ≤fmin＜fmax ≤ 954×106 Hz,and the difference between the maximum number and minimum number of frequency points is less than 65.This method can suppress the inter-modulation interference from the source,and provides an innovative idea for inter-modulation interference optimization.%详细分析了5阶互调干扰形成的一般机理,提出了一种降低无线网络互调干扰的频率优化算法:当小区频率组合满足935×106≤fmin＜fmax≤954×106 Hz,且最大频点号与最小频点号之差小于65时,该小区不可能出现由于频率组合所导致的5阶互调干扰.本方法从源头上规避了频率组合不当所导致的互调干扰,为无线网络互调干扰整治提出了新思路.
