Interference Mitigation Method in Hybrid D2D and Cellular Network

Abstract

This paper studies the effect of Device-to-Device interference in cellular networks. The focus of this study is the underlay inband interference resulting from sharing the same frequency. We propose a new mechanism that alleviates the effect of the additional interference in this hybrid system. Utilizing this interference mitigation method does not violate the frequency allocation of the cellular network. The quality of the studied network is evaluated using signal to interference plus noise ratio (SINR). The proposed approach reduces the interference levels in the uplink mode by 55%.
