System-level Simulation Methods and Implement for Ultra-dense Network with Small Cell

Based on the full understanding of the basic theory in wireless communication system-level simulation and Small Cell network, the 3D dual strip model of Small Cell is achieved, and a system-level simulation platform using the Visual Studio 2010 for ultra-dense network with Small Cell is built. The dual strip model has been verified, and the impact of three kinds of power control scheme proposed by 3GPP on ultra-dense network with Small Cell has been analyzed on the simulation platform. The simulation results of power control coincide with the theoretical analysis, which confirms the platform has met the requirements of the system design. Furthermore, the overall performance of Small Cell-based ultra-dense networks can be evaluated through the simulation platform, which benefits us to deploy Small Cell and optimize the performance of the ultra-dense networks.
