    Blockchain-based computing and wireless communication resource joint management double auction model by Yan SUN, Ao XIONG, Chengling JIANG, Wei WANG, Dongxiao YU, Shaoyong GUO

    Published 2022-11-01
    “…In wireless communication networks, the stock of spectrum, computing, storage and other resources at the edge was limited.The traditional decentralized and exclusive resource allocation resulted in weak resource reuse capability and low utilization rate.At the same time, it was difficult to ensure the fairness of resource sharing in the traditional resource scheduling process due to the lack of trust between the owners.First, a double auction model of computing and wireless communication resource joint management based on blockchain was proposed.In the model, a resource market was established, in which resource buyers and sellers allocated resources through double auctions.Secondly, blockchain was used to store the resource information of buyers and sellers to solve the mutual trust problem of all parties in the network.Finally, the experimental simulation was carried out to verify that the proposed model effectively improved the system performance and resource utilization efficiency.…”

    DropBlock based bimodal hybrid neural network for wireless communication modulation recognition by Yan GAO, Jian SHI, Shengyu MA, Bolin MA, Guangxue YUE

    Published 2022-05-01
    “…As an intermediate step of signal detection and demodulation, automatic modulation recognition played a momentous role in wireless communication system.Aiming at the low recognition accuracy of existing automatic modulation recognition methods, a bimodal hybrid neural network (BHNN) was proposed, which utilized complementary gain information contained in multiple modes to enrich feature dimensions.The improved residual network was connected in parallel with the bidirectional gated loop unit to construct a bimodal hybrid neural network model, and the spatial and temporal features of the signal were extracted respectively.The DropBlock regularization algorithm was introduced to effectively suppress the influence of over fitting, gradient disappearance and gradient explosion on the recognition accuracy in the process of network training.Using bimodal data input, the spatial and temporal characteristics of signals were fully utilized, and the network depth was reduced through parallel connection.The model convergence was accelerated, and the recognition accuracy of modulated signals was improved.In order to verify the effectiveness of the model, two public datasets were used to simulate the model.The results show that BHNN has high recognition accuracy and strong stability on the two datasets, and the recognition accuracy can reach 89% and 93.63% respectively under high signal-to-noise ratio.…”
