Successive Interference Cancellation for Ultra-Dense 5G Heterogeneous Network

Abstract

Interference Cancellation (IC) is an emerging technique for interference mitigation and network performance enhancement. Successive Interference Cancellation (SIC) has prominence among existing IC Techniques due to architectural similarity with traditional hardware for reduced cost effects. Moreover, SIC supports the transition to Fifth Generation (5G) heterogeneous networks environment due to flexible hardware compatibility. Therefore, in this study, we cover a detailed analysis of SIC in a multi-tier heterogeneous network through the system and channel-level mathematical modeling. Moreover, we simulated the heterogenous network environment to evaluate SIC success probability based on the number of users and Signal-to-interference-plus-Noise Ratio (SINR). Our results depict SIC as a potential promising IC solution for a heterogenous network.
