| Summary: | 碩士 === 國立臺灣師範大學 === 電機工程學系 === 104 === We consider the Device-to-Device (D2D) communication is likely to be established in non-ideal condition. The new downlink interference mitigation mechanism is proposed to enhance the overall system capacity on the premise of guaranteeing the links quality of macrocell user equipments (MUEs). We simulate the result of interference-suppression-area (ISA) and orthogonal resources allocation scheme with multiple D2D user equipment (DUE) that is called conventional scheme. This paper proposes a location recommendation and power adjustment (LR&PA) algorithm for DUEs to manage the interference from base station (BS) to DUEs and DUEs to MUEs when sharing same resources. We compared the two strategy about LR scheme and showed the strategy of LR by considering distance is more practical for users and hence this strategy is adopted by our proposed system. Numerical results show that our proposed algorithm is better than the conventional scheme in terms of DUE capacity. The loss of MUEs capacity is small compared to the gain of DUE capacity. The system capacity can thus be obviously improved.
