With the orthogonal polarization, layout of antenna arrays is optimized to ensure high channel isolation of antenna arrays’ different ports. The simulated results show the designed antennas having gain of 10.8 dBi, 11.8 dBi and 17.6 dBi respectively for S-band, X-band and Ku-band incidence. The side-lobe level (SLL) for S-band is -23.5 dB with return loss bandwidth of 50 MHz, while Ku-band antenna is -18 dB with bandwidth of 600 MHz respectively. And the bandwidth of circular polarization axial ratio (AR) less than 3 dB is around 1.1% for X-band. The isolation is better than - 40 dB among different ports of all arrays. Furthermore, the designed antennas can be flexibly covered on curved cylinder surface, maximum radiation gain is 2.4dBi, which is better than that of flat when the bending radius is 600mm for S-band. The proposed flexible microstrip antenna can be applied for conformal antennas, which shows great potential for flexible electronic device.","PeriodicalId":305812,"journal":{"name":"International Conference on Electronic Information Technology","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121457779","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 algorithm dynamically allocates the statistical length of NDA-EVM according to the coherence time of the fading channel. Under the limitation of constant transmit power, the maximum modulation order suitable for the current channel is obtained from the calculated EVM value. The NDA-EVM statistical length of the channel in the algorithm of this paper can be dynamically changed according to the channel fading characteristics, and the EVM value can reflect the channel change in real time; in addition, according to the derived EVM analytical formula in the fading channel, it can predict the transmission of data with any modulation order in the current channel environment High performance, accurately select the maximum modulation order suitable for the current channel, and reduce the number of adjustments of the modulation order. Both theoretical analysis and simulation show that: compared with the traditional adaptive modulation algorithm based on signal-to-noise ratio (SNR-AM), the algorithm in this paper has better performance in terms of modulation order selection, channel fading speed and channel coherence time change speed. So there is also a higher spectrum efficiency.","PeriodicalId":305812,"journal":{"name":"International Conference on Electronic Information Technology","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117152510","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}

Temperature compensation technology is the most important to design a high precision band gap reference source. In recent years, new high order temperature compensation technologies have been proposed. For example, segmental compensation technology, curvature compensation technology, and subthreshold compensation technology are common compensation means. In this paper, a new compensation method is proposed which is to generate the compensating current through the self-opening characteristic of the depletion-mode transistors. It can obtain a band gap reference source with high order compensation.

However, the large computation, high resource consumption, and slow inference speed of these algorithms severely limit their practical applications. Specifically, these algorithms struggle to meet the real-time tracking demands of resource-limited scenarios such as mobile devices and drones. Therefore, this paper proposes a pure Siamese-based, lightweight object tracking algorithm based on sparse attention. The proposed algorithm significantly improves tracking speed without significantly sacrificing tracking accuracy, making it suitable for practical resource-limited scenarios while still achieving good tracking performance. The proposed algorithm achieves a success rate of 76.3% and a normalized precision of 82.1% on the TrackingNet dataset, at the same time, it achieves a high inference speed of more than 100FPS, which exceeds the mainstream algorithm.","PeriodicalId":305812,"journal":{"name":"International Conference on Electronic Information Technology","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129071569","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}
