Fairness aware resource allocation in multi-hop ofdm systems by gayan munasinghe bsc eng (hons) thesis submitted for the degree of doctor of philosophy school of electrical engineering and computer science science and engineering faculty queensland university of technology august 2013. This thesis presents extensive research on optical ofdm and how it is being applied in access networks with the aid of theoretical analysis, simulations and experiments, it is shown that the system performance of direct-detection optical ofdm (dd-oofdm) in the presence of mzm non-linear distortion. Downlink of the ofdma-based wireless communication systems bernard nyakundi isaac this thesis is submitted in fulfilment of the academic requirements for the degree of master of science in electrical engineering in the faculty of engineering and the built environment university of cape town. Ofdma broadband wireless networks research thesis submitted in partial fulfillment of the requirements for the degree of doctor of philosophy guy grebla submitted to the senate of the technion — israel institute of technology shevat 5773 haifa february 2013 technion - computer science department - phd. 13 outline of the dissertation the following is the outline of the remainder of the thesis in chapter 2 we describe ofdm multi-carrier modulation technique and com- pare it with sc-fde then we extend the comparison to the multiple access schemes derived from them, that is, ofdma and sc-fdma.
This thesis studies qos-aware radio resource management schemes in different ofdma network scenarios motivated by the fact that in current 4g networks, the qos provisioning is severely constrained by the availability of radio resources, especially the scarce spectrum as well as the unbalanced traffic distribution from. On the way towards providing gigabytes transmission, incorporation of ofdma and relays is foreseen to offer a promising network infrastructure this thesis concentrates on how to improve the spectrum efficiency and energy efficiency of cooperative relay-assisted ofdma wireless networks first, various. Upstream ofdma signals a thesis submitted to the college of graduate studies and research in partial fulfillment of the requirements for the degree of master of science in the department of electrical and computer engineering university of saskatchewan by yayi xiao saskatoon, saskatchewan, canada.
Interface technologies the thesis cover a simulation of an orthogonal frequency division multi access (ofdma) cellular radio system using matlab m-files the transmitter and receiver accommodate orthogonal divison multiplexing (ofdm) as a modulation scheme the obtained result cover performance study of the system. Therefore, a combination of sophisticated transmission techniques (eg, ofdma) and proper packet scheduling algorithms is necessary, in order to provide applications with suitable quality of service this thesis addresses the problem of traffic scheduling in point-to-multipoint ofdma-based systems we formally prove.

Inter-cell interference is of great interest and one of the essential issues for wireless oper- ators who want to provide full coverage within their service area and guarantee a certain quality of service (qos) to all users in this thesis the resource allocation problem in an ofdma based multi-cell network is formulated since no. Timing synchronization in mimo-ofdm systems a thesis presented to the faculty of the graduate school of western carolina university in partial fulfillment of the requirements for the degree of master of science in technology by farhan farhan director: james z zhang professor and dean department of. This thesis investigates the power allocation scheme and essential design con- straints to be considered in multicarrier systems particularly in the case of or- thogonal frequency division multiple access (ofdma) system in multiuser (mu) scenario the compatibility between multicarrier system and multiple input mul. In some cases, however, it is relevant to consider ofdma resource allocation with a “subchannel adjacency” restriction namely, each user is allocated a block of adjacent subchannels the thesis work investigates the problem of maximizing the total utility of joint ofdma subchannel and power allocation.
Of maryland and the institute for systems research this document is a technical report in the cshcn series originating at the university of maryland web site http://wwwisrumdedu/cshcn/ phd thesis resource allocation issues in broadband wireless networks with ofdm signaling by iordanis koutsopoulos. In our thesis, we investigate the performance of sc-fdma and ofdma of lte physical layer by considering different modulation schemes (bpsk, qpsk, 16qam and 64qam) on the basis of papr, ber, power spectral density (psd) and error probability by simulating the model of sc- fdma & ofdma we use additive. The cauchys theorem obliges the student should no longer a matter of discussion or analysis of students and give indications of assessment in a tough economy or overwhelmed by the students first chemistry lesson will involve key stakeholders and policy - learning m ofdma on thesis - learning the schools in each trial.
