Although numerous essays have researched PPM applied to optical fiber, the PPM process with additive white Gaussian noise (AWGN) was not mentioned. In this paper, a relatively simple model was constructed for 2-bit message signals passing through the AWGN channel. While encoding the baseband signals, Gray Code was adopted to encode them in each period separated into four equal parts. Afterward, they all passed through the AWGN channel, and the constellation of baseband signals and received signals was performed in MATLAB. Then we applied the minimum distance identification method to find the estimated baseband signals. Finally, the PPM signal-tonoise ratio (SNR) was obtained based on previous probability errors. Executing the codes in MATLAB, we got the baseband signals, constellation, and SNR function that can all be directly shown in the figure. In general, our work filled the gap of the PPM method sending over the AWGN channel. This can also become the preliminary foundation for a broader range of applications using PPM to implement the whole communication process with AWGN.","PeriodicalId":336892,"journal":{"name":"Neural Networks, Information and Communication Engineering","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114486108","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The security and reliability of software have become important challenges that researchers must deal with. Fuzzing is a way of detecting vulnerabilities by providing unintended inputs to the target software and observing the final running results. During these years, fuzzing has proven its effectiveness in software security testing. But a large number of fuzzing tools rely solely on runtime information while testing software. Achieving static vulnerability prediction for programs in advance can greatly improve the efficiency of fuzzing. Vulnerability prediction aims to obtain the possibility of vulnerabilities in different parts of the program. The existing vulnerability prediction methods are relatively simple for feature extraction between basic blocks. We design a novel model combining self-attention mechanism and convolutional neural networks, which can extract and integrate the internal information of functions. Compared with the state-of-the-art V-Fuzz, our recall can be improved by 9.7 percentage points, and the accuracies of K-100~K-1000 can be higher than 90%.","PeriodicalId":336892,"journal":{"name":"Neural Networks, Information and Communication Engineering","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114055842","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed system uses the MPU9150 inertial sensor to obtain measurement data and the CC2530 microprocessor as the main control chip for data acquisition and processing. In the proposed system, the Pedestrian Dead Reckoning (PDR) algorithm is used to determine the step size based on the fusion expression between the walking frequency variance and acceleration, and the quaternion method is used to estimate pedestrian orientation angle. In order to reduce the error caused by the drift of the accelerometer and gyroscope, the extended Kalman filter is employed to correct the original data. The experimental results show that the positioning error of the proposed system is less than 1.6 m in 100 m. Thus, the proposed method can achieve high accuracy in the disaster relief personnel positioning in an underground coal mine.","PeriodicalId":336892,"journal":{"name":"Neural Networks, Information and Communication Engineering","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124425993","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The oscillator is composed of two inverters, comparators, controllable switches, capacitors and resistors. The comparator generates output voltage by comparing the capacitor voltage value and the reference voltage value. At the same time, it controls the working state of the switching MOS tube to complete the cyclic charge and discharge of the capacitor. The two groups of capacitors charge and discharge alternately, and then produce continuous oscillation waveform. The high-frequency clock is realized by alternating comparison between bilateral comparator and bias voltage. The advantage of this mode is that the oscillation frequency is only related to the charging time, but has nothing to do with the discharge time. There is no need to consider the influence of the discharge time delay on the frequency. In this paper, the coarse adjustment of the accuracy of the oscillator is realized by adjusting the charging current of the capacitor, and then the output of the oscillator is accurately adjusted by selecting the capacitance value of the capacitor.","PeriodicalId":336892,"journal":{"name":"Neural Networks, Information and Communication Engineering","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114281051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
