Research of Resource Allocation Technology Based on MIMO Ultra Density Heterogeneous Network for 5G

Abstract

With wireless device extensively application and continuing to enlarge accessing network, energy and spectrum resources are required more widely. Therefore, the purpose of this paper is to improve the resources, spectrum and energy efficiency of the ultra-density heterogeneous cellular network by using existing technologies, such as enhancing frequency spectrum utilization ratio orthogonal frequency division multiplexing (OFDM), and combatting channel fading performance MIMO etc. This paper proposes a method to decrease the whole system power consumption by deploying low power cellular with multi antennas, max system capacity and coverage. Simulation results show that the method can decrease system power consumption, enhance throughput and improve system performance. Therefore, multi- antenna ultra-density network resource allocation scheme is effective.
