EM-based blind LDPC identification in multipath channels by Yu LIU, Fanggang WANG, Jingwen ZHANG, Bo AI, Zhangdui ZHONG

“…As the advent of cognitive radios,blind encoder identification has attracted increasingly attentions since it plays an important role.The existing works mainly focus on additive white Gaussian noise (AWGN) channel,while the blind identification in multipath scenarios has not been sufficiently investigated.Considering the blind low density parity-check (LDPC) codes identification in the presence of unknown multipath fading channel,a likelihood-based classifier was proposed using the expectation maximization (EM) algorithm to obtain the maximum likelihood estimates of the unknown parameters.Then,an average log-likelihood ratio (LLR) estimator was adopted to classify the unknown encoder.Numerical results show that the proposed algorithm provides promising identification performance in multipath channels,especially in the low signal-to-noise ratio region.…”

Teaching Evaluation Algorithm Based on Grey Relational Analysis by Xiaoying Zhang, Xiuying Yang, Jing Yang

“…Grey correlation analysis uses grey correlations to describe the strength, magnitude, and order of relationships among factors. The data sequence of the drmined data is used as a reference data string, and the data sequence matrix of each influence factor is used as a control data matrix to calculate the correlation between the data sequence and the reference of each factor in the control data matrix. …”

Implementation architecture of mimic security defense based on SDN by Zhen-peng WANG, Hong-chao HU, Guo-zhen CHENG, Chuan-hao ZHANG

“…To deal with the attacks employing unknown security vulnerabilities or backdoors which are difficult for traditional defense techniques to eliminate,mimic security defense (MSD) that employs “dynamic,heterogeneity,redundancy (DHR)” mechanism can increase the difficulty and cost of attack and uncertainty of system so as to improve network security.Based on the software defined networking (SDN),an implementation architecture of MSD was proposed.First,diverse functional equivalent variants for the protected target were constructed,then leverage the rich programmability and flexibility of SDN to realize the dynamic scheduling and decision-making functions on SDN controller.Simulation and experimental results prove the availability and the intrusion tolerant ability of the architecture.…”

Zero-correlation zone complementary sets based on iteration by LI Yu-bo, XU Cheng-qian

“…Based on orthogonal matrices and interleaving iteration,two constructions of zero correlation zone comple-mentary（Z-complementary） sets were presented.The Z-complementary sets proposed not only have ideal auto-correlation and cross-correlation in a zone,but also have larger set sizes compared with the conventional comple-mentary sets.Moreover,their set sizes can achieve the theoretical bound.…”

Noise-attention-based forgery face detection method by Bolin ZHANG, Chuntao ZHU, Qilin YIN, Jingqiao FU, Lingyi LIU, Jiarui LIU, Hongmei LIU, Wei LU

“…With the advancement of artificial intelligence and deep neural networks, the ease of image generation and editing has increased significantly.Consequently, the occurrence of malicious tampering and forgery using image generation tools is on the rise, posing a significant threat to multimedia security and social stability.Therefore, it is crucial to research detection methods for forged faces.Face tampering and forgery can occur through various means and tools, leaving different levels of forgery traces during the tampering process.These traces can be partly reflected in the image noise.From the perspective of image noise, the noise components reflecting tampering traces of forged faces were extracted through a noise removal module.Furthermore, noise attention was generated to guide the backbone network in the detection of forged faces.The training of the noise removal module was supervised using SRM filters.In order to strengthen the guidance of the noise removal module, the noise obtained by the noise removal module was added back to the real face image, forming a pair of supervised training samples in a self-supervised manner.The experimental results illustrate that the noise features obtained by the noise removal module have a good degree of discrimination.Experiments were also conducted on several public datasets, and the proposed method achieves an accuracy of 98.32% on the Celeb-DF dataset, 92.61% on the DFDC dataset, and more than 94% on the FaceForensics++ dataset, thus proving the effectiveness of the proposed method.…”
