Virtual cell forming algorithm based on interference fair and multi-dimensional cooperation for ultra-dense network
Published 2017-09-01“…Virtual cell is identified as one of factors affecting the system performance in ultra-dense network where the interference is complex with the increasing density of cells and the resource allocation strategies of different dimensions were coupled in overlapped virtual cells.Therefore,aiming at designing the edge weight of virtual cells,an algorithm considering the resource allocation in advance was proposed by taking interference fair power allocation,MU-MIMO operation and cooperative transmission into account simultaneously.Based on the proposed scheme of weight,the overlapped virtual cells could be formed by the proposed clustering algorithm named pairwise maximum weights.The simulation results demonstrate that the proposed algorithm can improve the sum-rate performance of the network effectively at a low complexity.…”

Joint time and beam domain non-orthogonal multiple access
Published 2021-04-01“…In order to improve the system’s ability to accommodate connected devices, a joint time and beam domain non-orthogonal multiple access (NOMA) scheme was proposed, which was suitable for millimeter wave massive multiple-input multiple-output (MIMO) systems.The correlation and difference of the users’ channel were utilized to realize beam-domain NOMA, and sparse spreading technology was utilized to realize time-domain NOMA.With the optimization goal of improving the communication reliability of the system, optimization problem of the joint domain sparse access matrix design was constructed and solved.Finally, the access matrix was reconstructed based on the channel quality of the joint domain, and the interference cancellation operation was added to the message passing algorithm (MPA), which reduced the decoding complexity and improves the communication reliability.…”

Blind decoding method for a multi-cell massive antenna array system
Published 2016-08-01“…In order to overcome the pilot contamination and reduction of decoding performance resulted by neighbouring cell pilot sequences reuse in multi-cell massive array MIMO system,a blind decoding method based on ICA was proposed.The proposed blind decoding method used ICA to separate the received signals of multi-cell users without using pilot sequences.Thus,pilot contamination was avoided and decoding performance would be optimized.Every user’s angle-of-arrival(AOA)was estimated for recognizing the desired user signals and overcoming the uncertainty of signals separated by ICA.The analytical performance and numerical results show that the proposed method has a better performance compared to MMSE decoding and blind decoding method based on singular value decomposition(SVD).…”
