The overlay in-band device to device (D2D) scheme can be used by cellular user equipments (CUEs) and D2D user equipments (DUEs) to transmit the uplink and D2D data in the channel. The CUEs experience in-band emission interference (IEI) from the DUEs that transmit D2D signals in the adjacent channels. This paper investigates the IEI impact in D2D-enabled cellular networks and evaluates the cellular system performance by deriving the coverage probability and average data rate of typical CUE under different DUEs densities. Further, the intra-cell IEI and inter-cell IEI are separately examined to calculate the dominating interference in the system. Moreover, we propose density-based strategy (DBS) to mitigate IEI in D2D-enabled networks and evaluate the data rate gain. The reduction percentage of DUEs that can be served for each time slot is derived as a trade-off metric of the strategy. The results show the IEI impact is significant and should be considered to evaluate the system performance accurately. We evaluate the IEI impact by changing the DUEs density and DUEs transmission power. Additionally, a remarkable result finds that the intra-cell and inter-cell IEI dominate the typical CUE coverage probability similarly at low DUEs density, whilst at high DUEs density the intra-cell IEI does. The DBS results depict the remarkable improvement of the typical CUE data rate and define the upper bound of the data rate that can be achieved by DBS.
