A family of linear codes with three weights

arXiv (Cornell University) (2016)

Yan Yang Fei Li Qiuyan Wang

Recently, linear codes constructed by defining sets have attracted a lot of study, and many optimal linear codes with a few weights have been produced. The objective of this paper is to present a class of binary linear codes with three weights.

On the k-Error Linear Complexity of Binary Sequences Derived from the Discrete Logarithm in Finite Fields

Complexity (2019)

Zhixiong Chen Qiuyan Wang

Let be the finite field with q = p r elements, where p is an odd prime. For the ordered elements , the binary sequence σ = ( σ 0 , σ 1 , …, σ q −1 ) with period q is defined over the finite field as follows: σ n = {0, if n = 0, (1 − χ ( ξ n ))/2, if 1 ≤ n < q }, σ n + q = σ n , where χ is the quadratic character of . Obviously, σ is the Legendre sequence if r = 1. In this paper, our first contribution is to prove a lower bound on the linear complexity of σ for r ≥ 2, which improves some results of Meidl and Winterhof. Our second contribution is to study the distribution of the k ‐error linear complexity of σ for r = 2. Unfortunately, the method presented in this paper seems not suitable for the case r > 2 and we leave it open.

Recognition Influence of Different Acousitc Characters between Male and Female Speakers

Proceedings of the 2018 2nd International Conference on Computer Science and Artificial Intelligence (2018)

Liying Zhao Qiuyan Wang Xin Dang

The extraction of speech features is a key technology in the voiceprint recognition system. Correct rate of distinguishing identity of speakers is an important indicator to estimate a feature extraction method. In this paper, we firstly discuss the impact of different phonetic features on speaker recognition between different sexes. Steps and algorithms for obtaining Mel frequency cepstrum coefficient (MFCC), linear predictive cepstral coefficient (LPCC) and two improved MFCC speech features are also introduced in detail. Based on the experimental data presented in this paper, the above mentioned speech features are analyzed and compared theoretically. Experimental results show that recognition ability of male voice is better or worse than that of female voice, according to the feature coefficient is proposed by LPCC algorithm or by MFCC and its improved algorithms, respectively.

On the Linear Complexity of Legendre Sequences Over F<i><sub>q</sub></i>

IEICE Transactions on Fundamentals of Electronics Communications and Computer Sciences (2014)

Qiuyan Wang Dongdai Lin Xuan Guang

In this paper, the linear complexity and minimal polynomials of Legendre sequences over Fq have been calculated, where q = pm and p is a prime number. Our results show that Legendre sequences have high linear complexity over Fq for a large part of prime power number q so that they can resist the linear attack method.

Asymptotically Optimal Codebooks Derived From Generalised Bent Functions

IEEE Access (2020)

Qiuyan Wang Yang Yan

Codebooks are required to have small inner-product correlation in many practical applications, such as direct spread code division multiple access communications, space-time codes and compressed sensing. In general, it is difficult to construct optimal codebooks. In this paper, two kinds of codebooks are presented and proved to be optimally optimal with respect to the Welch bound. Additionally, the constructed codebooks in this paper have new parameters.

Book Retrieval Method Based on QR Code and CBIR Technology

Journal on artificial intelligence (2019)

Qiuyan Wang Dong Haibing

It is the development trend of library information management, which applies the mature and cutting-edge information technology to library information retrieval. In order to realize the rapid retrieval of massive book information, this paper proposes a book retrieval method combining QR code with image retrieval technology. This method analyzes the visual features of book images, design a book image retrieval method based on boundary contour and regional pixel distribution features, and realizes the association retrieval of book information combined with the QR code, so as to improve the efficiency of book retrieval. The experimental results show that, the books can be retrieved effectively through the boundary contour and regional pixel distribution features, the book information can be displayed through QR code, readers can be provided with fast and intelligent massive book retrieval services.

PCA-SVM Based Fault Prognosis for Flue Gas Turbine

Jie Ma Qiuyan Wang Aiming Dong

In this paper, a multivariate fault prognosis approach based on statistical process monitoring (SPM) methods and time series prediction for flue gas turbine was proposed. A principal component analysis (PCA) model using sample data under normal state was built. Firstly, fault is detected by squared prediction error (SPE) index, then predicted by SVM model. With development of fault process, the SPE will produce a corresponding change and carry important fault information, so calculate statistics of SPE can be characterized and predict the trend of fault and level. A case study on the flue gas turbine shows the efficiency of the proposed approach.
