INTEREFERENCE MANAGEMNET IN COGNITIVE RADIO NETWORKS Xxxx Xxxxxxxxx-Xxxxxxxx Centre for Telecommunications Research School of Natural & Mathematical Sciences King’s College London Doctor of Philosophy June 2013 This thesis is dedicated to my parents for their love and endless support. Acknowledgements Completing my PhD degree was probably the most challenging part of my life. The best and worst moments of my doctoral journey have been shared with many people. It has been a great privilege to spend several years in the Centre for Telecommunications Research (CTR) at King’s College London, and its members will always remain dear to me. At the end of my thesis I would like to thank all those people who made this thesis possible and an unforgettable experience for me. The highest gratitude goes to my supervisor, Xx Xxxxxxxx Xxxx Nakhai, for his support, patience, and encouragement throughout my PhD studies. It is not often that one finds a supervisor that always finds the time for listening to the little problems and roadblocks that unavoidably crop up in the course of performing research. His technical and editorial advice was essential to the completion of this dissertation and has taught me innumer- able lessons and insights on the workings of academic research in general. I could not have imagined having a better advisor and mentor for my PhD study. I am grateful to to my beloved parents; Xx Xxxxxxxx Xxxxxxxxx-Esfahani and Xxx. Xxxxxx Xxxxxx. Their love provided my inspiration and was my driving force. I owe them everything and wish I could show them just how much I love and appreciate them. I wish also to thank my brothers; Xx Xxxxx Xxxxxxxxx-Esfahani and Xx Xxxxxxx Xxxxxxxxx-Esfahani for their endless love and encouragement. I would like to thank my former colleague, Xx Xxxx Xxx Xx for his valuable assistance and support through out my PhD. Last but not least, to those who indirectly contributed in this research, your kindness means a lot to me. Thank you very much. Xxxx Xxxxxxxxx-Xxxxxxxx London, U.K. May 2013. Abstract Radio spectrum is becoming increasingly scarce as more and more devices go wireless. Meanwhile, studies indicate that the assigned spectrum is not fully utilised. Cognitive radio technology is envisioned to be a promising solution to address the imbalance between spectrum scarcity and underutilisation. Cognitive radio enables the unlicensed (secondary) user to establish a communication link in licensed (primary) spectrum on the condition that there is no or minimal interference to the primary user. The interference management has become an important topic in cognitive radio in order to manage and fulfill the regulatory constraints. The management of interference is, unquestionably, required to treat and quantify all the interference produced by the cognitive transmission at the primary users. In order to manage this interference, the secondary users must be able to adjust their parameters to fulfill these constraints. In addition, the performance of contemporary multicell wireless networks is limited by intercell interference (ICI), due to cochannel transmission in other cells. This per- formance degradation is especially severe for users close to the cell-edge. As a solution, in this thesis different cognitive beamfomring techniques are proposed by deploying cognitive cells on the primacy cells boundaries to support the primary cell-edge users as well as servicing the secondary users. This thesis proposes interference management techniques based on cognitive beam- forming in a cellular network. We have identified conditions and proposed different techniques for optimal usage of radio spectrum, by allowing coexistence on the same spectrum resources between primary and cognitive users. Deploying cognitive cells on

PROFESSIONAL DEVELOPMENT AND EDUCATIONAL IMPROVEMENT A. The Board agrees to implement the following:
MEDICAL DEVICES This Article applies when the Goods and/or Services involve UC purchasing or leasing one or more medical devices from Supplier, or when Supplier uses one or more medical devices in providing Goods and/or Services to UC. Medical Device as used herein will have the meaning provided by the U.S. Food and Drug Administration (“FDA”) and means an instrument, apparatus, implement, machine, contrivance, implant, in vitro reagent, or other similar or related article, including a component part, or accessory which is: (i) recognized in the official National Formulary, or the United States Pharmacopoeia, or any supplement to them; (ii) intended for use in the diagnosis of disease or other conditions, or in the cure, mitigation, treatment, or prevention of disease, in man or other animals, or (iii) intended to affect the structure or any function of the body of man or other animals, and which does not achieve any of its primary intended purposes through chemical action within or on the body of man or other animals and which is not dependent upon being metabolized for the achievement of any of its primary intended purposes. Supplier warrants that prior to UC’s purchase or lease of any Medical Device or Supplier’s use of any Medical Device in providing Goods and/or Services hereunder, Supplier will: (i) perform security testing and validation for each such Goods and/or Services or Medical Device, as applicable; (ii) perform a security scan by an anti-virus scanner, with up-to-date signatures, on any software embedded within any Goods and/or Services or Medical Device, as applicable, in order to verify that the software does not contain any known viruses or malware; (iii) conduct a vulnerability scan encompassing all ports and fuzz testing; and (iv) provide UC with reports for (i) – (iii). Supplier warrants that all security testing performed by Supplier covers all issues noted in the “SANS WE TOP 25” and/or “OWASP Top 10” documentation. Throughout Supplier’s performance of this Agreement, Supplier will provide UC with reasonably up-to-date patches, firmware and security updates for any Medical Device provided to UC, and any other Medical Device used in the course of providing Services, as applicable. All such patches and other security updates will be made available to UC within thirty (30) days of its commercial release or as otherwise recommended by Supplier or Supplier’s sub-supplier, whichever is earlier. Supplier warrants that all software and installation media not specifically required for any Medical Device used by Supplier or Goods and/or Services delivered to UC under this Agreement as well as files, scripts, messaging services and data will be removed from all such Goods and/or Services or Medical Device following installation, and that all hardware ports and drives not required for use or operation of such Goods and/or Services or Medical Device will be disabled at time of installation. In addition, Medical Devices must be configured so that only Supplier-approved applications will run on such Medical Devices. Supplier agrees that UC may take any and all actions that it, in its sole discretion, deems necessary to address, mitigate and/or rectify any real or potential security threat, and that no such action, to the extent such action does not compromise device certification, will impact, limit, reduce or negate Supplier’s warranties or any of Supplier’s other obligations hereunder. Supplier warrants that any Medical Device provided to UC, and any other Medical Device used in the course of providing such Goods and/or Services, meet and comply with all cyber-security guidance and similar standards promulgated by the FDA and any other applicable regulatory body. If the Goods and/or Services entail provision or use of a Medical Device, Supplier will provide UC with a completed Manufacturer Disclosure Statement for Medical Device Security (MDS2) form for each such Medical Device before UC is obligated to purchase or lease such Medical Device or prior to Supplier’s use of such device in its performance of Services. If Supplier provides an MDS2 form to UC concurrently with its provision of Goods and/or Services, UC will have a reasonable period of time to review such MDS2 form, and if the MDS2 form is unacceptable to UC, then UC in its sole discretion may return the Goods or terminate the Agreement with no further obligation to Supplier.
