Investigation of filter bank based device-to-device communication integrated into OFDMA cellular system

Device-to-Device communication has been a hot research topic in the recent years. Among different D2D use cases, the integration of D2D and conventional cellular network is one of the most attractive schemes. This approach has been investigated in recent academic and standardization studies, since such a combination improves the efficiency of the overall system in both resource and power domains. It also improves the coverage of the cellular network and improves the cell edge performance. In this paper, such a system combining D2D and OFDMA/SC-FDMA based cellular network is investigated. The D2D integrated OFDMA system performance is investigated, emphasizing the interference analysis. Besides, a filter bank based multicarrier (FBMC) scheme is introduced for the D2D integrated system for the purpose of interference reduction.
