移动通信网选择无干扰信道组的新型方案

A New of a Spectrum-Efficient Interference-Free Frequency Allocation Scheme for a Cellular Radio System

提出了一种在移动通信网中选择无干扰信道组并使频谱利用率达到最高的新型算法。讲叙了这种算法的基本原理和计算流程，较文献［１］由ＧＥＲＷＬＤ．Ｋ．ＣＨＡＮ和ＳＡＭＹ．Ａ．ＭＡＨＭＯＯＤ介绍的矩阵式列表行删除法进一步改进为矩阵式列表头删除法，在无同频干扰、无邻道干扰、无三阶互调干扰的条件下，频谱利用率大约较文献［１］方法提高了１０％左右。最后还给出了计算机分配的结果。

In this paper,attempts are made to describe a novel spectrum efficient and interference free frequency allocation scheme,which provides an operation free from co-channel interference as well as adjacent channel inteieference and third-order intermodulation interference. Compared with the scheme in [1],the one in question raises frequency utilization by about ten per cent.
