Performance evaluation on key techniques for 5G enhanced mobile broadband by Longchang ZHU, Xiaodong JI, Xinran ZHANG, Quxin LI

“…The 5G eMBB scenario puts high requirements on performance such as spectrum efficiency and system capacity.It was proposed to introduce technologies such as massive MIMO and millimeter-wave communication,and combine heterogeneous networks to improve system performance,because traditional technologies cannot bring about corresponding performance improvement.At the same time,there are few simulation evaluation results for the key technologies of the eMBB scenario,and the performance advantages of each technology cannot be explained from the perspective of simulation.The performance of massive MIMO with different antenna numbers by building a system-level simulation platform were evaluated,and the impact of the density and bias of micro BS in the mmWave frequency to the performance based on the results in the heterogeneous networks was summarized.It has great refer-ence value for parameter configuration and network construction of 5G network.…”

AAT model based channel estimation for mmWave massive MIMO systems by Shujuan YU, Rong LIU, Yun ZHANG, Na XIE, Liya HUANG

“…To solve the problems of temporal correlation and susceptibility to noise in millimeter wave massive MIMO channels, which result in decreased channel estimation accuracy, a novel channel estimation method based on an improved temporal convolutional network was proposed.The channel matrices obtained from simulation were feed into the system as two-dimensional image data.The temporal correlation was utilized for feature fusion and an attention in attention network was constructed to enhance the system’s ability to extract deep channel features.Then, AAN was integrated into the temporal convolutional network for training.Finally, the system outputted a denoised two-dimensional image, namely, the channel estimation matrix.Simulation results demonstrate that the proposed method not only exhibits good performance and complexity compared to conventional channel estimation methods but also maintains robustness when the test scenario changes.…”

Resource optimization of secure energy efficiency based on mmWave massive MIMO-NOMA system with SWIPT by Fei ZHAO, Wanming HAO, Gangcan SUN, Yiqing ZHOU, Fei WANG, Yi WANG

“…The secure energy efficiency (SEE) problem was investigated for the millimeter wave (mmWave) multiple input multiple output (MIMO) non-orthogonal multiplex access (NOMA) systems with simultaneous wireless information and power transfer (SWIPT) in the presence of multiple legitimate receiver (LR) and an eavesdropper.LR was first grouped according to the channel state information and the cluster heads of each group were selected,then the LR of each cluster was served by each beam with NOMA and hybrid precoding technology.Based on this,a SEE maximization problem was formulated by optimizing power allocation and power splitting factors.The Dinkelbach algorithm and first order Taylor approximation were proposed to transform the original non-convex problem into a convex one,and an iterative algorithm was developed to solve it.Finally,numerical results show that the proposed scheme can effectively improve the SEE.…”
