Statistical interference description in 4G mobile communications networks

Routing multiple signals is a capital goal for an operator. For that, network's generations' architectures are continuously reviewed in order to overcome various encountered challenges. Efforts remain however limited despite notable introduced enhancements. Operators must guarantee sufficient protection for every terminal even when multiple signals are simultaneously routed. The offered quality in each case will be indicated to see how the solution becomes difficult when cell's size goes shorter. Unfortunately, we will show how various added signals appear jointly with those useful ones. These added and unwanted parts define interference and affect needed signals. Quality manifests a decrease when customers move from wide and clearer space to a narrower one. This situation characterizes particularly urban contexts i.e. cities. In response to these challenges, technicians try to enhance the established solutions giving a better Quality of Service (QoS). From one mobile network's generation to another, cell's radius becomes smaller. Recently, we hope to approach punctual sites as previewed in D2D communications. Operators look to provide their customers satisfaction. They aim mainly increasing the offered data rates. The aim of this paper is to verify that the received power in radio mobile communications follows Rayleigh distribution. The rest of this paper is organized as follows. Section II will recall the data rate enhancements. Interference problem is described in second mobile network's generation up to fourth's one in section III. Section IV gives simulation results showing a perfect correspondence between theoretical and practiced approaches. Finally, the last section concludes the paper.
