PAPR reduction in F-OFDM system by using cluster scrambling code word shifting / Aidatul Julia Abd Jabar and Azlina Idris
No full textFiltered-OFDM (F-OFDM) is one of the proposed candidate for 5G system. In order to support the diversity in services, it requires the capability to support the multiple asynchronous sub-band transmission. However, the multicarrier transmission systems with different sub-carriers are suffer from high Peak-to-Average Power Ratio (PAPR) of the transmit signal. Consequently, the major problem of the F-OFDM system is the high PAPR value in the system that causing the performance degradation due to the various distortions. This paper presents, a method based on manipulation of the codeword by altering its structure known as Cluster Scrambling Codeword (CSC) is proposed to achieve better PAPR reduction. This is a new formulation on bit data sequence shifting technique, which can give better PAPR reduction compared to conventional scheme. The simulations result show that CSC gives 27.08% at 7.0dB which is better PAPR reduction performance compared to the conventional F-OFDM system
Poynting vector meter / Azlina Mohd Idris, Hasni Abdullah and Ruziah Mat Amin
No full textPoynting vector meter is a meter that is used to measure loss density in watt/m2 by multiplying two signals of electric field strength E and magnetic field strength H. The two signals come from a probe consists of a small coil for measuring H and sharp pins for measuring E. The directions of E and H are arranged to be perpendicular to each other in order to omit the effect of sin 0. The report consists of four main parts: Power circuit, Probe, Poynting vector meter ( practical electronic circuit) and Simulation of circuit on computer. To check up the circuit, the probe is fixed on a lossy conductive surface to sense the electric and magnetic field that will be the input to the poynting vector meter circuit and the output will be the loss density in watt / m 2 for different positions of the lossy conductor

Mevlana İdris Zengin evaluation of children's literature works in kind
No full textEğitim Bilimleri Enstitüsü, Ortaöğretim Sosyal Alanlar Eğitimi Ana Bilim Dalı"Mevlâna İdris Zengin'in Çocuk Edebiyatı Türündeki Eserlerinin Değerlendirilmesi" adını verdiğimiz bu çalışma, yazarın çocuk edebiyatı alanında yazdığı -yayınına ulaşılabilen- kırk adet eserlerini kapsar. Çalışmanın "çocuk" ve "çocuk edebiyatı" kapsamında olması, çalışmada "çocuk ve çocuk edebiyatı" na dair tanımlamaları ve bu tanımlamaların edebiyatımızdaki seyrine dair kısa bir bölümü gerekli kılmıştır. Mevlâna İdris Zengin'in çocuk edebiyatı alanındaki yerini ve serüvenini tespit edebilmek amacıyla çalışmanın ikinci aşamasında, yazarın çocuk edebiyatı alanındaki eserlerinin tematik incelemesi yapılarak bu alandaki yeri belirlenmeye çalışılmış, 1980'li yıllarda yaşanan toplumsal olayların çocuk edebiyatına olan yansımaları incelenerek Mevlâna İdris Zengin'in dünya görüşü ve çocuklar için yazma sebepleri tespit edilmeye gayret edilmiştir. Mevlâna İdris Zengin ile ilgili verilerin tespiti ve temini aşamasında yazara dair kapsamlı bir biyografiye ulaşılamamıştır. Bu eksikliğin giderilmesine küçük bir katkıda bulunabilmek için çalışma içeriğine, Mevlâna İdris Zengin'in biyografisi de eklenmiştir. Çalışmanın asıl bölümünü oluşturan "Bulgular ve Yorumlar" kısmında; Mevlâna İdris Zengin'in çocuk edebiyatı alanında yazdığı eserlerin içerik, yapı ve dil çözümlemelerine yer verilmiş ve yazarın çocuklara iletmek istediği mesajlar üzerinden belirlenen kavramlar incelenmiştir. Bu çalışmada yer alan, Mevlâna İdris Zengin'in çocuk edebiyatı alanında yazdığı eserlere dair içerik yorumları ve yapı analizleri klasik yaklaşımlarla ele alınmıştır. Çalışmada, Mevlâna İdris Zengin'in eserlerindeki içerik ve yapı unsurları bütüncül bir bakışla sınıflandırılmaya çalışılmıştır. Çalışmanın son bölümünde çalışmalarımız süresince faydalandığımız kaynaklar yer alır. "Ekler" bölümünde bulunan, Mevlâna İdris Zengin'in incelenen eserlerine dair oluşturulan "Mevlâna İdris'in Eserlerinde Farklı Kavramların Görünüşü", "Mevlâna v İdris'in Eserlerindeki Meslek Gruplarının Dağılımı", "Mevlâna İdris'in Eserlerindeki Mekânların Dağılımı" ve "Mevlâna İdris'in Eserlerindeki Ana Kahramanların Dağılımı" tabloları yazarın çocuk edebiyatı evreninin sınırlarını belirlemeyi amaçlar. Mevlâna İdris'in eserlerinde çocukları birden fazla kavram, duygu ve değer üzerine düşünmeye sevk etmesi, sorgulatması ve çözüm yollarını buldurtması yazarın eserlerinin özgün yanları olarak karşımıza çıkar. Farklı kavram alanlarını çocuk edebiyatı içerisinde değerlendiren yazar, bu kavramları çocuğa göre ele alır ancak çocukları kavramlar ekseninde bir yetişkin edasıyla düşündürür. Kavramlar etrafında düşünme örgüsünü ören çocuklar yazarın eserlerinde harekete geçer. Düşüncelerin kahramanlar tarafından davranışa dönüştürülmesi ve davranışların kavramlar etrafında şekillenmesi Mevlâna İdris'i çağdaşı olan çocuk edebiyatçılarından ayıran bir özelliktir. Sıradan olayların eserlerinde çok fazla yer almaması da yazarın, çocukların hayal gücünü geliştirmeye yönelik çabalar olarak değerlendirilebilir.This study, named as "The evaluation of Mevlana İdris Zengin's works the author has written in the genre of children literature" , covers the forty pieces of works the publication of which can be reached and the author has written.

Performance analysis of packet scheduling algorithm for femtocell-macrocell scenario in LTE network / Muhammad Naqiuddin Sahrani, Darmawaty Mohd Ali and Azlina Idris
No full textThe increasing number of users has led to various challenging issues especially when providing coverage to the users in the building. The indoor coverage deteriorates since the signal cannot pass through the wall completely. The coverage signal will become weaker and affect the Quality of Service to the customers. Operators have tried to overcome this problem by providing small cells (femtocells) inside the building. In this paper, we have investigated the performance of packet scheduling algorithms; Proportional Fairness (PF), Round Robin (RR), Priority Set (PSS), Blind Equal Throughput (BET) and Maximum Throughput (MT) in the LTE environment where a dual stripe block type apartment is included in the network topology. Each apartment is assumed to have two femtocells where each cell is serving five customers. Meanwhile, the number of users in the Macrocell is varied between 50 to 200. Three types of services are delivered during the simulation which are VoIP, video and FTP. The simulations results are presented in the terms of throughput and delay. It can be concluded that PF and RR algorithms are the most compatible to be deployed in the Macrocell-Femtocell environment
Improving space-time-frequency MIMOOFDM with ICI self-cancellation scheme using least square error estimator / Nur Farahiah Ibrahim, Zahari Abu Bakar and Azlina Idris
No full textChannel estimation techniques for Multiple-input Multiple-output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) based on comb type pilot arrangement with least-square error (LSE) estimator was investigated with space-time-frequency (STF) diversity implementation. The frequency offset in OFDM effected its performance. This was mitigated with the implementation of the presented inter-carrier interference selfcancellation (ICI-SC) techniques and different space-time subcarrier mapping. STF block coding in the system exploits the spatial, temporal and
frequency diversity to improve performance. Estimated channel was fed into a decoder which combined the STF decoding together with the estimated channel coefficients using LSE estimator for equalization. The performance
of the system was compared by measuring the symbol error rate with a PSK-16 and PSK-32. The results show that subcarrier mapping together with ICI-SC were able to increase the system performance. Introduction of channel estimation was also able to estimate the channel coefficient at only 5dB difference with a perfectly known channel
