Comparison of FFR+IFR and IFR Models with Different Frequency Reuse Factors in Cellular Networks

Abstract

With the development of information network transmission, how to efficiently complete frequency reuse has been studied by many scholars. Frequency reuse refers to reusing the same frequency in a digital cellular system. Generally, limited frequencies are divided into several groups. As we all know, fractional frequency reuse (FFR) and integer frequency reuse (IFR) are classical frequency reuse methods in cellular networks. The combination of FFR method and IFR method to find the best model has attracted the attention of researchers at home and abroad. Therefore, through the fusion and combination of the four models, this paper will first introduce two frequency reuse methods, IFR and FFR, as well as the combination of these two methods and the calculation methods of these two methods. Through Matlab software modeling and simulation, according to the average capacity results, study the impact of different user numbers on the average capacity of the central area and the edge area. The experimental results provide a new idea for future practical applications.
