Sum-rate maximization in MIMO NOMA system with imperfect CSI by Yanjing SUN, Yang LIU, Jiasi ZHOU, Qi CAO, Song LI

“…In order to solve the problem of maximizing the sum rate under the constraints of transmission power limitation and users’ rates requirements,precoder and receiver were devised by combining multiple-input multiple-output (MIMO) and non-orthogonal multiple access (NOMA) based on imperfect channel state information (CSI).To take advantage of successive interference cancellation (SIC) techniques to eliminate interference from weak user’s signal,each data stream of the strong user needed to decode the corresponding weak user’s signal.Since the problem formed was non-convex,it was converted into the problem with the difference of two convex functions (D.C.) by using semi-positive definite programming and first-order Taylor expansion,and a penalty function was used to solve the constraint of the rank of the precoding covariance matrix.The simulation results show that compared with the orthogonal multiple access technology,the proposed D.C.algorithm can improve system sum rate.…”

k-error linear complexity of q-ary sequence of period p² by Chenhuang WU, Chunxiang XU, Xiaoni DU

“…Based on element statistics in a matrix,a new efficient computing method for computing the k-error linear complexity of q-ary sequence of period p<sup>2</sup>was proposed,where p,q were odd primes and q modulo p<sup>2</sup>was primitive.A general result and a concrete proof were showed.To verify the correctness of the result,two kinds of q-ary sequence of period p<sup>2</sup>were illustrated.Because the new method does not need iterative calculation and when it is implemented by program and compared with existing algorithms,the results show that the proposed new algorithm is significantly more efficient in calculating k-error linear complexity of q-ary sequence of period p<sup>2</sup>.…”

Novel node upgradation strategy for migration to elastic optical networks by Xiaodong FU, Yongcheng LI, Gangxiang SHEN

“…For migration from dense wavelength division multiplexing (DWDM) networks to elastic optical networks (EON),it is required to upgrade the traditional reconfigurable optical add-drop multiplexer (ROADM) to the new-generation ROADM that supports flexible grids.However,for a large-scale optical network,it is generally impossible to upgrade the ROADM nodes all in once; rather,they would be upgraded gradually.For this,it is critical to study different strategies for selecting the ROADM nodes to be upgraded.Also,for the interconnection between different generations of ROADM,the sub-band virtual concatenation (VCAT) technique was employed to enable an optical channel to be established via traversing different types of nodes.An integer liner programming (ILP) model and an efficient heuristic algorithm were developed to jointly select the ROADM nodes to upgraded and assign spectrum resources.Simulation studies show that the proposed strategy for the upgraded node selection is efficient to perform close to the ILP model in terms of the maximum number of FS used in the whole network.…”

Ternary polynomial based key management scheme for wireless sensor network by Zhi-tao GUAN, Yue XU, Jun WU

“…A ternary polynomial based key management (KMTP) scheme was proposed,which is effective in cluster based wireless sensor networks.Firstly,the base station will give each node one unique identi ier to ensure the validity of the node.Then,algorithm of the inner-cluster and inter-cluster key pre-distribution based on the ternary polynomial of the same order was stated,which can ensure the value of the cracking threshold is bigger than the number of nodes of a clus-ter and all clusters separately,which means it's very hard to be cracked even all nodes of a cluster or all clusters are com-promised.To assure the communication security,inter-cluster multi-hop routing mechanism was designed based on con-structing secure conjunct neighbor table.Finally,the updating parameter and the updating authentication number were in-troduced in rekeying phase.The analysis shows that the proposed scheme can meet the security requirement of key man-agement,and it also has less computation cost and storage cost than the existing schemes.…”
