Improved CPD based DOA estimation of nested array
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.…”

Proxy re-signature scheme based on isomorphisms of polynomial
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.…”
