Abstract

Considering the ever-increasing bandwidth demand of the users in cellular networks, there have been ongoing investigations of new standards to support users' requirements and increasing their performance in mobile networks. One of the more promising mobile communication standards for the Fourth Generation (4G) cellular systems is the Long Term Evolution Advanced (LTE-Advanced) standard. This technology provides an order of magnitude higher data rates and improves the users' quality of service by using a number of technologies including Coordinated Multipoint (CoMP) processing. In this paper, we have used the Discrete Event System Specification (DEVS) formalism to model a mobile network using two approaches of CoMP: namely, coordinated scheduling/beamforming and joint processing. The DEVS approach confirms that these approaches decrease the interference level resulting in cell edge users experiencing higher level of performance.
