    Joint power control for untrusted relay cooperation-based confidential communication by Wen-jiang FENG, Wei-heng JIANG, Yi-na DENG, Yang YUAN

    Published 2014-11-01
    “…The scenario that multiple cell-edge mobile stations (MS) all without direct-links to the base station (BS) but have confidential messages in the uplink in the presence of untrusted relay (UR) cooperation was considered.In order to implement the secure communication between BS and multiple MS,destination-based jamming (DBJ) scheme was adopted.With the assumption that all MS had fixed transmit power,the joint UR and BS power control which aims at maximizing system sum secrecy rate was discussed.For this problem,analysis indicated that it was equivalent to joint access control and power allocation problem thus its NP-hard.Through problem relaxation,a suboptimal MS access control and alternatively power allocation algorithm was provided.This algorithm is proved to have polynomial complexity and can converge to at least a suboptimal solution for original problem.Simulation results show that compared with the benchmark algorithms,the proposed suboptimal algorithm is better in the achievable secrecy rate performance.…”

    AI based scheme on voice service quality evaluation and assurance by Guangyu LI, Yanping LIANG, Li YU, Kun WANG, Yangming CHEN, Sijia LIU

    Published 2021-05-01
    “…The voice service is one of the mainstream services under the telecommunications network.The mainstream voice service quality evaluation method in the industry is to compare the voice and audio of the transceiver and calculate the POLQA MOS, which is the standard benchmark for voice quality analysis.For telecom operators, perceive voice service quality efficiently without any infringement of user privacy, and carry out precise service quality assurance, is one of the key tasks.A system using mathematical statistics and neural network to learn the mapping between voice service feature data from network side and voice quality from user side to generate evaluation model with high accuracy and precision was proposed.On this basis, the system made use of data information from multiple fields including wireless network user level and cell level, to analyze reasons and work out solutions for poor service quality, so as to assure service quality efficiently and accurately.The result shows that the scheme has achieved good practical application results.…”

    Autonomous deployment and energy efficiency optimization strategy of UAV based on deep reinforcement learning by Yi ZHOU, Xiaoyong MA, Fuxiao GAO, Wei LI, Nan CHENG, Ning LU

    Published 2019-06-01
    “…Utilizing a UAV to build aerial mobile small cell can provide more flexible and efficient access services for ground terminal users.Constrained by the coverage and limited energy of the UAV,it is necessary to study how to build a fast,efficient and energy-saving air-ground collaborative network.To deal with complex dynamic scenarios,the UAV needs to deploy an optimal coverage position,and meanwhile reduce both path loss and energy consumption in the deployment process.Based on the deep reinforcement learning,a strategy of autonomous UAV deployment and efficiency optimization was proposed.The coverage state set of UAV was established,and the energy efficiency was used as a reward function.Depth neural network and Q-learning were used to guide UAV to make autonomous decision and deploy the optimal position.The simulation results show that the deployment time of the proposed method can be effectively reduced by 60%,while the energy consumption can be reduced by 10%~20%.…”
