Indoor wireless signal coverage and enhancement based on passive reconfigurable intelligent metasurface
Published 2022-12-01“…Reconfigurable intelligent metasurface (RIS) is a new type of artificial electromagnetic metamaterial, which can control the frequency, amplitude, phase, polarization, propagation direction and wave type of electromagnetic wave flexibly.In the field of wireless communication, RIS can be used to reconstruct the wireless communication channel to achieve blind coverage of wireless signals and improve the communication quality.First, the development and research status of RIS, the key technologies and application scenarios of RIS were summarized and analyzed.Then, a new passive RIS was proposed to realize the characteristics of the aperture reconfiguration and beam reconfiguration through passive coding and splicing principle, which had the advantages of low cost, low power consumption and low complexity.Finally, the blind area coverage enhancement experiment of indoor wireless signal based on passive reflection metasurface was carried out.The effectiveness of passive splicing metasurface in wireless communication blind coverage scenarios was proved by comparison between simulation and field measurement.In addition, for 5G/6G millimeter wave communication, the passive RIS with double-layer cross dipole elements was designed and applied to typical indoor L-shaped corridor scene to verify the enhancement effect of indoor wireless signal coverage.…”

A cost-effective and miniaturized SPN deployment strategy for group customer dedicated lines
Published 2023-07-01“…With the change of networking mode in the evolution of 5G network, SPN is faced with the limitations of ubiquitous coverage, which leads to the long access distance of the passenger dedicated line customers.Based on the operator's benefit-oriented construction idea, in order to solve the network benefit problem in the process of further deepening SPN coverage.Three sink deployment strategies were proposed for different scenarios, taking the empirical value cost of typical configurations as an example.By building a simulation environment, Gaussian mixture model was used to simulate the distribution characteristics of group customers, and the relationship between the total number of customers, the number of sinking SPN devices and customer coverage in sparse, common and dense scenarios were analyzed, and the network benefits of different sinking strategies were tested.The simulation results show that strategy 3 only faces the area coverage with high sinking efficiency when the total number of customers is 600, and the maximum coverage rate can only reach 55.27%.However, with the increase of customer points, the maximum coverage rate of strategy 3 can reach 82.71%, which has obvious coverage advantages.At the same time, the average number of sunk equipment can cover the highest number of customers, realizing the high coverage ability under the condition of ensuring high efficiency.…”

Design of microwave ceramic waveguide filter with high out-of-band suppression characteristics
Published 2021-04-01“…The design theory of ceramic waveguide filter was introduced, and then the combination structure of coupling through slot with shallow or deep coupling blind hole was designed, which could meet the requirements of positive and negative coupling bandwidth.By adjusting the cross coupling between 3~6 cavities, the symmetry of the filter transmis-sion curve was improved, and the near and far end band suppression of the filter was realized.Finally, a six-cavity ce-ramic waveguide filter for 5G base station was designed.In the process of optimizing the filter, the influences of the rela-tive position offset of the cross-coupling through slot and the length of the cross-coupling through slot on the transmis-sion zero position, the near end and far end out of band suppression characteristics of the filter were discussed in detail, and the relevant change rules were given.The performance indexes of the optimized filter were as follows, center fre-quency was 3.5 GHz, working bandwidth was 200 MHz, insertion loss ≤ 1.2 dB, return loss ≥ 17 dB, near end out of band rejection ≥ 25 dB, far end out of band rejection ≥ 51 dB.According to the structural parameters of the simulation model, the performance test results of the samples are in good agreement with the simulation results.…”

Optimal relay selection for full duplex SWIPT-NOMA systems with maximal throughput
Published 2021-05-01“…To improve the performance of 5G communication system, a full duplex Internet of things (IoT) relay system model was built by introducing the non-orthogonal multi-access (NOMA) technology.For the relay system of simultaneous wireless information and power transfer (SWIPT), it was considered that the relay node can harvest the energy of the source node, the self-interference signal of the loop channel and the free energy access point (EAP), and NOMA technology was used to forward the source node signal and its own signal to different destination nodes.Based on the model, a power distribution collaboration SWIPT relay selection strategy was proposed to optimize system throughput.Firstly, the problem model was established based on the constraints of communication quality of service and transmission power of source nodes.And then, the original nonlinear 0-1 programming problem was converted into a pair of coupling optimization problem by mathematical transformation, and the optimal relay selection of outer optimization problem was solved based on the optimal solution of the internal optimization problem.Finally, an optimal relay selection algorithm was used to maximize system throughput.Simulation results show that the proposed model and strategy are superior to the traditional maximum-minimum relay selection schemes in terms of throughput gain, and the consideration of EAP can significantly improve the interrupt performance.…”
