    Improved CPD based DOA estimation of nested array by Sibei CHENG, Xiao LUO, Bochou JIANG, Yuting WANG, Huanyu WU

    Published 2021-08-01
    “…In order to avoid searching the peak value in space domain, when estimating nested array’s the direction of direction of arrival(DOA), the canonical polyadic decomposition(CPD) was applied into the nested array, namely using the one time singular value decomposition(SVD), bilinear mapping and tensor decomposition to obtain the steering vector matrix and arrival angle.However, the existing CPD algorithm only can be applied in noiseless environment, the algorithm was improved by utilizing SVD two times, and was made to be applied in both noiseless and noisy environments.The simulation results demonstrate that in the same signal to noise ratio(SNR) and snapshot, the DOA estimation algorithm of nested array based on the improved CPD has better performances and less running time than the MUSIC and space smoothing algorithms.…”

    Published 2019-08-01
    “…Recurrent neural network(RNN) has been used wildly used in machine learning field in recent years,especially in dealing with sequential learning tasks compared with other neural network like CNN.However,RNN and its variants,such as LSTM,GRU and other fully connected networks,have high computational and storage complexity,which makes its inference calculation slow and difficult to be applied in products.On the one hand,traditional computing platforms such as CPU are not suitable for large-scale matrix operation of RNN.On the other hand,the shared memory and global memory of hardware acceleration platform GPU make the power consumption of GPU-based RNN accelerator higher.More and more research has been done on the RNN accelerator of the FPGA in recent years because of its parallel computing and low power consumption performance.An overview of the researches on RNN accelerator based on FPGA in recent years is given.The optimization algorithm of software level and the architecture design of hardware level used in these accelerator are summarized and some future research directions are proposed.…”

    Proxy re-signature scheme based on isomorphisms of polynomial by Hui-xian LI, Lu SHAO, Liao-jun PANG

    Published 2017-02-01
    “…Most of the existing proxy resignature schemes were based on the hardness of big integer factoring,discrete logarithm,elliptic curve.However,none of them can resist the attack by a quantum computer.Motivated by these concerns,a new proxy resignature scheme was proposed.By employing secret affine transformations and homogeneous polynomials,the proposed scheme could implement the signature transformation with high-efficiency,and meanwhile it was secure against the attack by a quantum computer.The results of analysis showed that the proposed scheme was correct and consistent,and had the unforgeability in the random oracle model.Compared with the existing schemes,the proposed scheme not only inherits the resistance to quantum attack and high efficiency from the multivariate public key cryptosystems,but also has the properties of multi-use,transparent and private proxy.…”
