Abstract :
Frequency reuse is the critical means of increasing a cellular system´s capacity, yet it also has an inherent interference problem. Mitigating the interference problem is the key to increasing the capacity of cellular networks. One important way to avoid interference is to assign the frequencies more efficiently. This paper discusses an algorithm of automatically assigning frequencies to optimize the interference based on the frequency reuse pattern, C/I ratio, number of cells, system demands, and the adjacent and co-channel interference requirements. The results of before and after application of the frequency assignment are also discussed. Finally, this paper shows that a significant interference reduction can be achieved by applying this algorithm
