This paper proposes a novel beam aggregation scheme for millimeter wave (mm-Wave) system under hybrid beamforming architecture, assuming one user equipment (UE) equipped with multiple antenna panels receives distinct beams from multiple transmission points (TPs) simultaneously. Further, system framework including channel state information (CSI) feedback scheme and scheduling algorithm is investigated...
In a three-dimensional (3D) multiple-input multiple-output (MIMO) system, the base station can use both horizontal and vertical spaces, transmitting spatial beam to users more accurately. This system has caught the attention of researchers in recent years. The existing research on the 3D MIMO technology is based on the assumption that the base station can acquire the ideal channel state information...
Heterogeneous Networks (HetNets) has attracted considerable attention since they can improve the system capacity and user throughput in Long Term Evolution (LTE)-Advanced system. However, due to the different coverage sizes for macro eNodeB (eNB) and pico eNB, the handover performance of UE will be impacted especially when the user equipment (UE) moves in medium or high speed in HetNets. Three metrics...
For multi-rectangle detection, this paper proposes a detection approach based on chain-code tracing. It improves the method of chain-code trace for getting rectangle contour based on geometric property of rectangle. Then divide this contour into four segments and determine rectangle by line fitting and ensure detect precision by affirm true rectangle using evidence collected. Numerical experiments...
