With the rapid development of signal processing technology, high performance ultra-long point FFT is required. This paper analyzes the characteristics of FFT algorithm, generalizes the two-dimensional decomposition algorithm to the multi-dimensional decomposition algorithm, and proposes a high-performance ultra-long point FFT hardware implementation architecture. This architecture implements the three-dimensional transpose operation by using the collision free bank addressing technology based on prime number banks. The synthesis results show that the operating frequency can reach more than 1GHz. The number of points supported and the performance in this paper are significantly improved compared with the existing research results.","PeriodicalId":219763,"journal":{"name":"2021 International Conference on Electronics, Circuits and Information Engineering (ECIE)","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129242322","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 filtering power divider includes three-layer substrates. The top layer substrate realizes a perfect magnetic conductor (PMC) using periodic plated vias and metallic patches. It is applied for packaging filter power divider composed of substrate integrated waveguide (SIW) and microstrip to avoid interference and losses induced by external radiation emission and internal radiation leakage. The middle layer substrate generates a gap layer. and the bottom layer substrate etch the slots on the metal plane and place a metal through hole in the middle of the metal layer to generate resonance and transmission zeros, and connect the microstrip to form a filter power divider circuit. The results show that FPD has multiple transmission zeros, the passband is 13.2 to 15.5 GHz, and an insertion loss of -4 dB. The return loss in the passband is less than -15 dB, and the isolation below is -16.5 dB.","PeriodicalId":219763,"journal":{"name":"2021 International Conference on Electronics, Circuits and Information Engineering (ECIE)","volume":"148 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116336707","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}

However, the majority of automatic detector of colon polyps in CT colonoscopy was got through offline training, which cannot be updated, when new samples were coming; simultaneously, polyp detection suffers from imbalanced data sets where negative samples (non-polyp) are dominant. Therefore, an online learning asymmetric approach was employed, which not only can update detector, but also can solve the problem of imbalanced data sets. Finally, experimental results show that the proposed algorithm can achieve good classification performance, and a shorter running time.","PeriodicalId":219763,"journal":{"name":"2021 International Conference on Electronics, Circuits and Information Engineering (ECIE)","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124668090","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}

Among these portable devices, electrocardiogram (ECG), blood pressure, and blood glucose are important parameters for health diagnosis. Therefore, in this work, based on the traditional 3-op-amp instrumentation amplifier, a front-end Electrocardiogram signal amplifier is designed. According to the characteristics in the bioelectric signal acquisition, a right-leg-driven (DRL) circuit is added to make the CMRR of the amplifier higher and improve the power-line-interference rejecting ability. The simulation result in LTspice indicates that the amplifier provides a gain about 36 dB with low noise about 6.08 $mu$ V. Also, the other parameters of the amplifier meet the requirements of ECG signal monitor and are suitable for wearable equipment.","PeriodicalId":219763,"journal":{"name":"2021 International Conference on Electronics, Circuits and Information Engineering (ECIE)","volume":"152 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123825691","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}

As people’s income and quality of life are constantly improving and their consumption level is gradually increasing, the quantity of household garbage is also growing rapidly. It is of great urgency to implement the classification and management of household garbage to make full use of garbage resources and reduce environmental pollution as well as land resource occupation. In order to conduct the classification and management work of household garbage more efficiently, this paper develops a garbage detecting system using a lightweight model MobileNetV3_Lite, which is promoted from MobileNetV3, as the backbone network to reduce computation and building up a YOLOV3-MobileNetV3_Lite detection model. The model successfully detects four categories of garbage, effectively and accurately determining the category and quantity of the waste. After the model is exported, deployed, and tested on NVIDIA Jetson Nano, the frame rate is up to 25. In the actual test, the accuracy for judging the category of garbage reached 94.56% and 90.91% for detecting the quantity of each category of garbage.","PeriodicalId":219763,"journal":{"name":"2021 International Conference on Electronics, Circuits and Information Engineering (ECIE)","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117101864","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}
