By equipping sensing and communication units on UAVs, they can execute sensing tasks and transmit the sensing information to the base station (BS) for environment sensing. Due to the mobility and dense deployment of UAVs, they can sense the environment with much lower cost compared to the BS sensing. We aim to minimize the network sensing cost by optimizing the UAV deployment and task assignment collaboratively. For this joint optimization problem, we propose an iterative mechanism to optimize the UAV deployment and task assignment iteratively. UAV deployment problem is modeled as a cluster problem and we utilize a K-means cluster algorithm to solve it efficiently. For task assignment problem, we propose a greedy algorithm to solve it with low complexity. Simulation results validate the effectiveness of our proposed method in different scenarios.","PeriodicalId":114868,"journal":{"name":"International Conference on Optoelectronic Information and Computer Engineering (OICE)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117102494","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}

First, take the envelope entropy as a fitness feature, and use the quantum genetic algorithm to calculate the two parameters [K, α] of VMD are selected adaptively. Secondly, the VMD with the optimized parameter [K, α] is used to decompose the fault vibration signal, and multiple intrinsic mode components (IMF) are obtained. Finally, Hilbert envelope spectrum analysis was carried out for the modal component with the lowest envelope entropy, and can effectively determine the fault type through the fault characteristic frequency. It is proved that this method is useful and can solve the effect of parameter setting on VMD.","PeriodicalId":114868,"journal":{"name":"International Conference on Optoelectronic Information and Computer Engineering (OICE)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129129851","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}

JPEG-LS is an algorithm that supports lossless and near-lossless compression. However, the decompression of JPEG-LS images is mostly implemented in a software environment. When decompressing multiple high-resolution images, the problems of decoding speed and resource consumption are more prominent. Therefore, the implementation of the JPEG-LS image decompression algorithm on FPGA is proposed in this paper, which divides the image into blocks and adopts a parallel processing structure. After the experiment on the hardware decoder, for the 1024*2048 test image, the designed hardware decoder can improve the original software decoding time by approximately 55%.","PeriodicalId":114868,"journal":{"name":"International Conference on Optoelectronic Information and Computer Engineering (OICE)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122924136","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}

In this paper, a novel distributed optical fiber acoustic sensor system is proposed, which can reduce the spectrum resources occupied by the combination of the above two technologies. The system continuously injects nonlinear frequency modulation detection pulses of different frequency ranges. The frequency response range of vibration is improved by frequency division multiplexing, and the spatial resolution is enhanced by nonlinear frequency modulation. Nonlinear frequency modulation also improves the sidelobe rejection ratio without loss of signal-to-noise ratio. In the experiment, eight frequencies were multiplexed using a 120MHz bandwidth. We achieved a spatial resolution of about 5m and a frequency response range of 1~20kHz on a 16.3km fiber.","PeriodicalId":114868,"journal":{"name":"International Conference on Optoelectronic Information and Computer Engineering (OICE)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127762120","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}

When it is equivalent to a linear array, it exhibits the characteristics of \"The middle spacing is large, and the spacing between the two sides is gradually reduced\", and there is an inverse density weighting phenomenon, which will lead to a high sidelobe of the FDAA beam. In order to further reduce the influence of sidelobe level and inverse density weighting, the amplitude weighting is carried out on the basis of the nonlinear frequency offset of the array element, but the amplitude weighting is realized by the attenuator in each channel, which will lead to the decrease of the antenna gain, which is generally used when the radar receives the signal. For the transmitter of antenna radar, this paper proposes a phase weighting method for nonlinear frequency offset.

In order to achieve the dynamic angular range reflected in the mounting error of MEMS gyroscope, the range of the NIKON-6D autocollimator has been extended from ±15' to ±9°by exploiting the relationship between the angular range and the structure of the reflector. In addition, in the software design, a common data acquisition serial port between CMOS camera and MEMS gyroscope was built. By integrating the angular rate measurements of the MEMS gyroscope with the sampling time, a uniformity of magnitude was obtained between the angular readings of the autocollimator and the angular rate readings of the MEMS gyroscope. Experimental verification shows that compared with precision three-axis angular rate output turntable, the relative calibration deviation of the MEMS gyroscope mounting error coefficient is less than 0.6%, and the platform benefits from the traceable reference of the autocollimator, which has the advantages of low maintenance evaluation rate and high stability, and can serve the long-cycle and high-efficiency MEMS gyroscope mounting error calibration and calibration process.","PeriodicalId":114868,"journal":{"name":"International Conference on Optoelectronic Information and Computer Engineering (OICE)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114385812","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 corresponding applications include sparse synthesis, management of aperture resources and targets allocation. However, due to the discrete weighting values as well as the corresponding non-deterministic polynomial computational complexity, most existing adaptive beamforming approaches are not suitable. Here, an algorithm based on simulated annealing optimization is proposed and the performances of binary weighted beamforming with one-dimensional and two-dimensional random arrays are numerically evaluated. According to the results with number of array elements ranging from 17 to 151, the side lobes can be reduced by 4.43 dB in average utilizing only around 66.7% of the total array elements while the width of the main lobe has increased by about 30%. For adaptive beamforming circumstances, an extra depth of up to 20 dB is achieved in presence of a preset jammer.
