Therefore, in this paper, we propose a method that can improve the equalization performance for received signals with noises.","PeriodicalId":359822,"journal":{"name":"2021 International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128814192","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}

By analyzing drivers’ bad driving behavior, it can help to avoid dangerous driving conditions, and also reduce traffic accidents. A system has been designed in this system that could simultaneously collect images of the roads ahead, and real-time images of the head, eyes, and face of the driver while driving. There were three subsystems constructed in this system: (1) Driver's visual state analysis system, (2) ECU message capturing and decoding system, (3) Driving behavior analysis system.Meanwhile, through integrating the information of the driver’s visual state analysis system with ECU message capturing and decoding system, the current system could detect and identify four types of bad driving behavior: (a) turning without flashing the turn signals, (b) Not looking in the rearview mirror when turning, (c) Distracted driving and (d) Fatigue driving. On top of that, the accuracy rates of \"turning without flashing the signals\" and \"without looking in the rearview mirror when turning\" were 89% and 87%, respectively, while the accuracy rates of distracted driving and fatigue driving were 82% and 79%, respectively.","PeriodicalId":359822,"journal":{"name":"2021 International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124546144","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 main advantages of this method compared to the conventional are the high accuracy of the model and the flexibility for lowering the complexity. These are achieved because the CNN models are trained to perform multiple small classification tasks instead of a single big classification task. This method makes retraining much easier. The five-fold cross-validation is applied to assess the performance for training and testing the model. To validate the model, actual Wi-Fi signals are used to test the model using Software Define Radio (SDR). The result shows the proposed method can accurately classify different packet formats and signal modulation types above 90%, even when different timing offsets occur.","PeriodicalId":359822,"journal":{"name":"2021 International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124667403","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}

After getting the answers, they will synthesize and analyze all the answers to figure out which physique the patient has. In the Traditional Chinese Medicine(TCM) clinic, due to time pressure, the doctor can only ask the patient a few questions, and then use other diagnostic methods to guess the cause, which can easily lead to misdiagnosis. This paper attempts to use machine learning, which has fast training and high accuracy, and the analysis model is closest to the decision tree of human intuition. It is combined with the TCM body mass scale to build an Intelligent Online Consultation System that can quickly and accurately analyze the patient's physique. The decision tree of this system shortens the TCM body mass scale, which originally had to answer 44 questions to get the physique result, to only 3 questions to know the patient’s possible physique. This system can be used with only one internet-connected device and network, can be cross-platform, and has an online learning function, which can be customized to improve accuracy. This system can assist doctors in seeing a doctor, and can also allow patients to track their physical conditions at home for more accurate medical treatment.","PeriodicalId":359822,"journal":{"name":"2021 International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124674273","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 completeness of the H.264/SVC bitstream is very crucial in achieving high quality video decompression. This is especially true in regard to the base layer which contains the important coding data. In this paper, we improve the quality of H.264/SVC video transmission by using the Space Time Block Code (STBC) technique. STBC is a technique to increase the reliability of the wireless transmission by transmitting multiple copies of the signal along multiple transmit antennas and is thus suitable for the need of H.264/SVC. We compared STBC with conventional SISO and MIMO techniques using the IEEE 802.11ac standard.
