    Coverage optimization algorithm and implementation based on computational graph for mobile communication network and IoT service by Haobin WANG, Wei HUANGFU, Yaxi LIU, Wei LIU

    Published 2019-06-01
    “…The research on the mobile communication network optimization for the Internet of things large connection and differential service quality has great significance.Mobile communication network optimization is a multi-parameter complex optimization problem with high computational cost function.In order to provide the basis for parallelization of operations,the calculation method of the coverage quality assessment of the mobile communication network based on the computational graph was introduced.Based on the calculation graph,the derivative calculation method of the coverage quality index was obtained,by back propagation to guide the optimization of the antenna parameters.The momentum method was used to accelerate the convergence speed of the optimization algorithm.The simulation results show that the algorithm is suitable for the coverage optimization in mobile communication network.…”

    Time hopping short reference carrier index differential chaos shift keying communication scheme by Hua YANG, Yu WANG, Siyuan XU, Guoping JIANG

    Published 2022-03-01
    “…In order to effectively utilize the transmission power of the reference signals in carrier index differential chaos shift keying (CI-DCSK), a novel time hopping short reference carrier index differential chaos shift keying communication system was proposed.Firstly, the symbol time was divided into multiple time slots, one of which was selected to send short reference signals according to the reference index bits.Then, analytical bit error rate expressions over additive white Gaussian noise and multipath Rayleigh fading channels were derived.Simulation results verify that the proposed scheme has a significant improvement in spectral efficiency, system energy efficiency and bit error rate performance.…”
