In order to improve the communication quality and ensure the correctness and reliability of the communication, the method of error control is usually used for error correction. Error control often adopts the technology of error correction code, which improves the reliability of information transmission by adding redundant information to the effective information code stream. RS code is a typical error correction code with strong error correction ability, which can correct both random errors and burst errors. On this basis, this paper studies the basic rules of RS code construction, designs a new type of codec system circuit for RS (35,27) code, and finally uses hardware description language to design the encoder and decoder, implementation and simulation verification. It has been verified that the RS encoding, and decoding system is stable and reliable, has excellent performance, strong error correction ability, strong scalability, and has a broad application space.","PeriodicalId":253792,"journal":{"name":"Conference on Optics and Communication Technology","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123089155","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}

UNet has become the de facto standard in various medical image segmentation tasks with great success. However, because the inherent local nature of convolutional operations makes UNet usually limited in explicitly modeling long-term dependencies, and because the huge parameters and computational complexity of UNet and its variants make UNet and its variants perform poorly for fast image segmentation in medical applications, we propose a new network structure (UNeCt) based on the UNet structure. U-sing a tokenized MLP in the latent space reduces the number of parameters and computational complexity, while being able to produce a better representation to aid segmentation. The network also includes skip connections between encoders and decoders at all levels. The results show that we achieve a good balance between the number of parameters, computational complexity and segmentation performance.","PeriodicalId":253792,"journal":{"name":"Conference on Optics and Communication Technology","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127289841","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}

Therefore, calculating the success rate of barrier coverage is of great significance in the study of wireless sensor network coverage. Due to the influence of environmental factors, wireless sensor nodes will be offset accordingly during the process of throwing. This paper mainly focuses on the success rate of line-based deployed barrier coverage under right-angle and polar coordinate systems that obey normal distribution and compares the success rate of barrier coverage under right-angle and polar coordinate systems through simulation. The experimental results show that the success rate of the line-based deployed barrier coverage increases as the offset decreases and the simulated success rate is almost lower than the analogue success rate, both in the Cartesian and polar coordinate systems when the experimental data meet the constraints. The simulated values are more consistent with the analogue values in the Cartesian coordinate system, but the deviations in the Polar coordinate system are larger.","PeriodicalId":253792,"journal":{"name":"Conference on Optics and Communication Technology","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132093656","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}

For four linear areas, we can get four feature vectors, each of which is computed based on two codes of the same linear area.
