We begin by outlining the obtained explicit expression of AED in multi-frequency system namely fractional frequency reuse (FFR), for single layer and two-layer SVC. We start with mathematical model for single-layer and two-layered SVC, where expected distortion of the SVC that depends on the trade-off between the probability of outage and quantization accuracy is derived. The novel performance measurement of AED is then used to measure the relationship between the average distortion rate, outage probability and channel allocation per area in multi-frequency systems. Analysis of AED for FFR shows that the two-layer SVC outperforms the single layer transmission with 60 percent lesser expected distortion at 20dB, and we deduced a system parameter for two layer SVC, that given minimum AED when the threshold distance is at 0.86km and 0.78km at 20dB and 0dB respectively. The analytical results are verified using the Monte Carlo simulations.","PeriodicalId":345344,"journal":{"name":"2020 IEEE 5th International Symposium on Telecommunication Technologies (ISTT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129570316","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 proposed unit-cell has a circular geometrical shape with a triple split-ring resonator (SRR) and stepped-impedance resonator (SIR) technique applied to provide better miniaturization factor. The operating frequency is controlled by the presence/absence of a perfect conductor switches. Employing nine switches, the frequency is controlled over the range (1–7) GHz providing a various range of resonance frequencies, frequency bands, and different bandwidths. The suggested metamaterial is simulated using Ansys Electronics Desktop simulator (HFSS), and MATLAB software is used to analyze the characteristics of the unit-cell in terms of permittivity, permeability, and the refractive index. The reflection and transmission coefficients are extracted to observe the behavior of the metamaterial. The results show a negative near-zero refractive index at a certain frequency range. The permeability and permittivity curves exhibit a single negative (SNG) and a double negative (DNG) operating region.","PeriodicalId":345344,"journal":{"name":"2020 IEEE 5th International Symposium on Telecommunication Technologies (ISTT)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129942563","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 amount received by them directly correlates with the cultivated paddy areas that include subsistence in fertilizers, seeds, and machinery. Hence, it is important for the Malaysian government to identify the exact areas that have been cultivated so that the subsidies will reach the targeted groups correctly. Currently, the surveying process is done manually by filed observer, which is a costly and tedious process. Hence, a remote sensing approach is proposed for an automated surveying system that semantically segments the satellite images of the paddy fields according to the intended class. A deep learning approach is adopted where a fully convolutional network with spatial pyramid pooling (SPP) module is designed to segment the images into four types of class, which are cultivated areas, uncultivated areas, backgrounds, and others. The encoder backbone of the network is based on VGG16, where the SPP module is comprised of four parallel branches of multiscale feature maps. The up-sample process is done through two layers of transposed convolution, where the output will be resized back according to the input image. The results show that the proposed network with SPP kernel set of 4x4, 5x5, 6x6, and 7x7 returns the best performance with a mean accuracy of 0.9869 and Jaccard index of 0.8326. The model faced its biggest training challenge when the clouds obstructed the surface information, which makes the areas uninformative. In the future, the network can be further improved by adding feed-forward layers and residual skip connections that help in reducing the zero gradient diminishing problem.","PeriodicalId":345344,"journal":{"name":"2020 IEEE 5th International Symposium on Telecommunication Technologies (ISTT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126523561","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}
