    Study on an effective integrated model of Ka-band mobile satellite channel by Juan WEI, Da LIU, Gang-qi TIAN

    Published 2012-11-01
    “…In order to describe the Ka-band mobile satellite communications channel fading features more realitically,a mobile satellite integrated channel model was proposed.The characteristics of the mobile satellite propogation channel were analysed in detail.Weather conditions,as well as multi-path fading and shadowing were taken into account as main influencing factors.On this basis,airspace channel model was built obeying the Gaussian distribution as well ground surface,which obey Rice,Rayleigh and Lognormal joint distribution.Then the integrated channel model was presented considering weather effects on condition that the two parts are independent each other in the influence of the channel characteristics.The mathematical analysis model and simulation model of the new integrated channel model were established respectively.Finally,the BER(bit error rate)performance was analyzed for different weather conditions and shadows.Compared with the theoretical BER,the integrated channel model in satellite mobile communication systems is correct and reasonable.…”

    D2D computation task offloading for efficient federated learning by Xiaoran CAI, Xiaopeng MO, Jie XU

    Published 2019-12-01
    “…Federated learning is a kind of distributed machine learning technique.The factor of communication and computation resource constraints at the edge node is becoming the performance bottleneck.In particular,when different edge node has distinct computation and communication capabilities,the model training performance may degrade severely,thus necessitating the joint communication and computation optimization.To tackle this challenge,a computational task offloading scheme enabled by device-to-device (D2D) communications was proposed,in which different edge node exchanged data samples via D2D communication links to balance the processing capability and task load,in order to minimize the total time delay for machine learning model training.Simulation results show that compared to the benchmark scheme without such D2D task offloading the training speed and efficiency of federated learning has be improved significantly.…”
