LTE-Advanced system based on orthogonal frequency division multiplexing (OFDM) can eliminate intra-cell interference since data are carried on the orthogonal subcarriers; however, it can not mitigate inter-cell interference (ICI) which affects the performance severely. Therefore, coordinated multiple point (CoMP) reception scheme was proposed to reduce ICI and improve the cell capacity for the uplink...
To further improve and satisfy the spectral efficiency requirements addressed in LTE-Advanced system, in this paper, a Coordinated Multi-Cell MU-MIMO scheme is proposed to achieve this goal, especially to enhance the cell-edge user(the 5% of user throughput) throughput substantially. In our proposed cooperative scheme, we adopt multi-cell block diagonalization (BD) algorithm to perform joint procession...
The blast load response of precise bolt finite element model was studied by LS-DYNA software. Firstly, the initial stress of thread was added by the dropping temperature method. Then the dynamic response and deformation damage of the bolt model were calculated by the elastic-plastic constitutive material equation and surface-surface contact algorithm, which calculating models including bolt joint...
LTE-Advanced system which based on orthogonal frequency division multiplexing (OFDM) can eliminate intra-cell interference but still can not mitigate inter-cell interference (ICI). Coordinated Multi-Point transmission/reception (CoMP) is one of the candidate techniques for LTE-Advanced systems to increase the cell average and cell edge user throughput in the both uplink and downlink. Although CoMP...
LTE-advanced system which based on orthogonal frequency division multiplexing (OFDM) can eliminate intra-cell interference but still can not mitigate inter-cell interference (ICI). In this paper, we propose a novel cooperative multi-cell multiple-input multiple-output (MIMO) scheme for LTE-advanced system to reduce ICI and improve the cell capacity. By sharing information such as data and channel...
