Hybrid precoding and power allocation for mmWave NOMA systems based on time delay line arrays
Published 2022-06-01“…Results:Simulation analysis:(1)The figure6(a)show that the SE of the proposed scheme is higher than that of the conventional phase-shifter modulation network with fully-connected and sub-connected hybrid precoding structures; In addition, the system SE of the fullconnected structure under the proposed scheme is better than that of the hybrid-connected and sub-connected structures.(2) the figure6(b) show that the EE of the system under the proposed scheme is also better than that of the conventional phase-shifter network-based and fully-digital precoding structures; Also, the system SE of the sub-connected structure under the proposed scheme is better than that of the hybrid-connected and fully-connected structures. (3) The figure7(a) show that the SE of the system increases as the number of antennas increases;The figure7(b)show that the EE of the system decreases as the number of antennas increases. (4) The figure8(a) and (b) show that compared with the mmWave orthogonal multiple access (OMA) system based on the time-delayed line array, and the proposed scheme can achieve better performance in terms of EE and SE.(5)the figure9(a) show that the performance of the proposed improved K-means user grouping algorithm is better than the K-means user grouping algorithm.Although the K-means can be done better based on the state information of the channel,the randomness of its initial cluster head will affect the convergence of the algorithm and the system performance. …”

Routing algorithm for MPLS traffic engineering in satellite network
Published 2011-01-01“…With regard to long transmission delay and dynamic topology characters in satellite network,a novel routing algorithm was proposed in multi-protocol label switching satellite network.The algorithm uses the prior knowledge of source-destination pairs,and link propagation delay is also considered.Based on time-varying topology snapshot of satellite network,initial link weight is defined as function of transmission delay and residual bandwidth.Both current request and future requests are in account when calculate critical degree.Thus traffic engineering is realized by link weight dynamic adjustment and critical links extension loaded,which guarantee resource utilized better.Simulation results demonstrate the algorithm performs better in terms of request reject ratio,total available flow,average hop and transmission delay of least interference paths.…”
