Uma análise de desempenho do Escalonador Adaptive Proportional Fair para redes heterogêneas LTE Advanced

Abstract

This work presents a performance evaluation of the scheduler Adaptive Proportional Fair (APF) based on simulations of heterogeneous LTE Advanced networks using the software Matlab. The present work makes a historical resumption of the development in the area of the networks, presenting the evolution between the traditional networks until the junction with the mobile networks. From this point on, some interference scheduling and coordination techniques are used to improve the transmission of users with bad conditions in these networks. Such techniques are compared through simulations to analyze characteristics of spectral performance, quality of service (QoS), fairness and transmission energy efficiency on the downlink side of a mobile network, making comparisons between network theory and wave propagation to the simulations. present in this work.
