The reflection spectrum of fiber Bragg gratings with a uniform modulation of the refractive index is accompanied by series of sidelobes at the adjacent wavelength. It is very important to minimize and, if possible, eliminate the reflectivity of these sidelobes. The design of fiber Bragg gratings used Coupled Mode Theory. The coupled mode equations were solved by the Transfer Matrix Method since it was considered as good approximation to calculate the spectral response of fiber Bragg gratings. Apodization techniques are used to get optimized reflection spectrum. The uniform FBGs with several types of apodization were modeled in this project It was proven that apodization profile could be reduced the sidelobes. In addition, each profile also has the bandwidth and the maximum reflectivity better than others.","PeriodicalId":428512,"journal":{"name":"2015 9th International Conference on Telecommunication Systems Services and Applications (TSSA)","volume":"178 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123177353","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}

Mechanically, the system is implemented by stepper motor, gear system and a turntable for positioning the AUT on azimuth and elevation angle. The user interface of system is realized by a keypad and LCD display. From the result, it shows that the realized antenna measurement tool can handle a patch antenna of 50gram weight with the deviation angle of 1°. Meanwhile for a patch antenna of 100gram weight, the deviation angle increases to be 2.5°. In addition, due to the torque of antenna, the deviation on elevation angle becomes larger for the elevation angle closer to 180°.","PeriodicalId":428512,"journal":{"name":"2015 9th International Conference on Telecommunication Systems Services and Applications (TSSA)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127782465","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}

Because adjacent cells employs the same frequency in universal frequency reuse scheme, interference between adjacent cells may degrade the bit rate, particularly at the cell edges. Inter-Cell Interference Coordination (ICIC) based on carrier aggregation as well as Coordinated Multipoint (CoMP) transmission and reception techniques have been considered as promising techniques to overcome the interference problem and to improve the bit rate at the cell edges. ICI problem can be mitigated by using different arrangements of frequency-bands allocations and possibly with different transmission power, distinguishing between the cell centre and the cell edge users. In this paper, mitigation of inter-cell interference using carrier aggregation (CA) and coordinated multipoint (CoMP) techniques are evaluated through computer simulaton. The simulation employs different frequency allocation schemes, fractional frequency reuse, different transmission powers, and different radio resource scheduling algorithms to evaluate and to enhance cell edge performance, bandwidth efficiency and throughput. The performance is evaluated in terms of SINR as a function of the number of femtocell users, and the separation distance from interfering cells. The performance is then compared between conventional technique, CA technique and the combined CA and CoMP techniques.","PeriodicalId":428512,"journal":{"name":"2015 9th International Conference on Telecommunication Systems Services and Applications (TSSA)","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121165788","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 development of FMCW-based SAR transmitter for Unmanned Aerial Vehicle (UAV) is the interest point focused in this paper. An UAV is a small aircraft that is operated remotely. The choice of components for SAR transmitter is considered to be as compact as possible so it could be installed in a UAV.

There are many methods that can be used to analyze electromagnetic waves like Method of Moment (MOM), Finite Element Method (FEM), Finite Volume Method, and also Finite Difference Time Domain (FDTD). FDTD is chosen because it has several advantages that are easy to understand has short development time and naturally explicit. In this work, FDTD will be used to modeling and comparing wave characteristic and propagation in 3D Cartesian and cylindrical coordinate. The size that used in 3D Cartesian structure is x = 60cm, γ = 30cm, and z = 120cm whereas the dimension in cylindrical structure is r = 60cm, q> = 30, and z = 120cm. The grid size of both structure is made equal so either Cartesian or cylindrical structure has identical Δt. TE mode is applied in this simulation with propagation along z-axis. The source for this simulation is sinusoidal wave modulated with Gaussian pulse with frequency 1GHz. The simulations are undertaken in some variations of condition. The first condition is for modeling free space in both Cartesian and cylindrical structure. The result is in the form of frequency cut-off for both structures. The second and the third are for modeling dielectric and conductive medium which objective is for observing the effect of adding these medium in wave propagation characteristic. The result from cylindrical structure will be analyzed and compared to the result of Cartesian structure.","PeriodicalId":428512,"journal":{"name":"2015 9th International Conference on Telecommunication Systems Services and Applications (TSSA)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125306671","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 work, Elliptic Curve and Keccak Hash Function were proposed to solve the problem. The Elliptic Curve is used for conducting device authentication such that there is no possibility for obtaining user fingerprint by unlegitimate device, while Keccak Hash Function is used for improving the user authentication process, such that the authentication process can be succeeded only if both password and fingerprint is authenticated. The result of experiment shows that the user authentication processing time decreased 35.06 ms-41.6 ms compared with the method proposed by Seung .etal, while the probability of obtaining the fingerprint and password using the proposed method is less than the previous method of 2-57.
