Recently, the Orthogonal frequency-division multiplexing (OFDM) is used for high-speed underwater acoustic communication because of its high efficiency in using wideband frequency and strong resistance to inter symbol interference (ISI). However, this modulation requires large-scale computation so each node consumes huge amount of power. When the power is insufficiency, the node may collapse. In order to solve this problem, optimized transmission and receiving algorithm are developed on an ARM9-based embedded system, which equipped with an additional DSP (TI C6748). The ping-pong processing and data transmission are realized by using a DMA address list, while the modulation is optimized by using the TI's DSP function library. The optimized transmission and receiving algorithm are implemented in underwater acoustic communication. Different pilots are applied to test the system performance. Low BER is achieved and power consumption is reduced.","PeriodicalId":191106,"journal":{"name":"Proceedings of the 2021 5th International Conference on Electronic Information Technology and Computer Engineering","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115075479","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}

This could be hard problems to classify radar emitters one from another through the basic parameters of Pulse Descriptor Words (PDWs). In this paper, we propose a feature extraction method of intercepted radar pulse train for constructing complex networks using Limited penetrable visibility graph (LPVG). In our algorithm, we selected four pulse trains of radar emitter as sample data to analyze the topological characteristics of four networks. Furthermore, the simulation results uncovered the inter-pulse train dynamical patterns which trigger the structure of network changing among PDWs. Meanwhile, the proposed algorithm is effective and feasible in classifying radar emitter signals. In a word, this paper described explored topological characteristics in networks constructed from pulse time series data, which provides a new angle to investigate the radar pulse train and provides a new effective means for feature extraction of radar emitter signals. The experimental results show that the features extracted by the method in this paper have good separability, and the results are visualized after feature extraction and classification of the four radar emitter signals in the experiment, which proves that the method has good results.","PeriodicalId":191106,"journal":{"name":"Proceedings of the 2021 5th International Conference on Electronic Information Technology and Computer Engineering","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116064017","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 number one cause of accidental injury to an elderly person or child is a fall. When there is a danger, it is difficult for the elderly to save themselves in time. Children, on the other hand, have the characteristic of being active, which makes them fall frequently during running resulting in different degrees of injuries to children. In recent years, deep learning algorithms have become a research hotspot in the field of graphic image processing, and the YOLO series of algorithms [1-3], as a classical algorithm in the single-stage target detection algorithm, has the accuracy comparable to the two-stage algorithm and the speed beyond the two-stage algorithm, this paper is using the Tiny-yolov3 algorithm model to detect human falls, which has the advantages of high detection accuracy and low computational complexity. By monitoring the trajectory of the human body in real time through the camera loaded on the trolley, the abnormal posture of the human body is detected and stays in certain positions for a long time to serve as a criterion for whether the human body has fallen or not. A better result is achieved, which can provide some reference for fall monitoring related research.","PeriodicalId":191106,"journal":{"name":"Proceedings of the 2021 5th International Conference on Electronic Information Technology and Computer Engineering","volume":"99 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129851740","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 efficiency and accuracy of the entire logging system will be directly affected by whether the signals captured by the downhole acquisition equipment can be transferred reliably and at a high rate to the surface receiver for data processing. Now, for the problems of slow cable transmission speed, signal attenuation, and severe distortion, the transmission system is studied in this paper based on orthogonal frequency division multiplexing (OFDM) technology. The logging cable telemetry system's overall plan is designed, and the OFDM communication system is completed according to IEEE802.11a physical layer standard, detailing the transmitter and receiver's circuit structure, functional roles, and implementation methods, and instituting each transmitter and receiver module using XILINX Field Programmable Gate Arrays (FPGA). Scrambler, convolutional encoder, interleaver, 16QAM modulator, IFFT module, insert CP module, and training sequence module is all included in the transmitter. Time synchronizer, CP removal module, FFT module, deinterleaver, demodulator, Viterbi decoder, and descrambler are all included in the receiver. RTL level simulation on the Vivado platform is used to verify the communication system. The results demonstrate that the communication time per frame of 128bit data communication is 130us and that this telemetry system can communicate at a rate of more than 7600Kbit/s without using a cable. The FPGA-based telemetry system has advantages over typical digital signal processor telemetry systems regarding communication rate and real-time performance.","PeriodicalId":191106,"journal":{"name":"Proceedings of the 2021 5th International Conference on Electronic Information Technology and Computer Engineering","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128359028","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}
