BoxTo my beloved family for their unconditional love and support.A mi querida familia por su cariño y apoyo incondicionales. 0 ABSTRACTThe owned spectrum allocation policy, in use since the early days of modern radio communications, has been proven to effectively control interference among radio communication systems and simplify the design of hardware for use at a known and fixed range of frequencies. However, the overwhelming proliferation of new operators, innovative services and wireless technologies during the last years has resulted, under this static regulatory regime, in the depletion of all spectrum bands with commercially attractive radio propagation characteristics. The vast majority of spectrum regarded as usable has already been allocated, thus...

Abstract-Signal detection of primary users for cognitive radios enables spectrum use agility. In normal operation conditions, the sensed spectrum is nonflat i.e. the power spectrum is not constant. A novel method proposed the segmentation of the measured spectra into regions where the flatness condition is approximately valid. As a result, an automatic detection of the significant spectral components together with an estimate of the magnitude of the spectral component and a measure of the quality of classification became available. In this paper, we optimize the methodology for signal detection for cognitive radios such that the probability that a spectral component was incorrectly classified is minimized. Simulation and measurement results show the advantages of the presented technique in different types of measured spectra.

“…These requirements for IMT-Advanced system or the fourth generation (4G) of cellular wireless standards are defined by international telecommunication union-radio (ITU-R). Currently, IMT-Advanced technology plan is generally viewed to have two main roads, specifically a conventional cellular-based (2G, 3G, 3G long term evolution (LTE), and LTEAdvanced) from the 3rd generation partnership project (3GPP), and an internet protocol (IP)-based (IEEE 802.16d or worldwide interoperability for microwave access (WiMAX) [2,3], IEEE 802.16e (mobile WiMAX) and IEEE 802.16m evolution) from the institute of electrical and electronics engineers (IEEE) [1,4,5]. Another point that is reasonably priced takes into account that high bandwidth (BW) mobile access leads to a better quality of experience for users, facilitating them to get more out of existing services, and opens the door for latest broadband systems.…”

“…Distributing high capacity by the more rapidly infrastructure of radio access technologies will improve the value of these services. Although the candidate IMT-Advanced technologies for spectrum use in frequency bands proclaimed by world radiocommunication conference 2007 is still a challenge to overcome [4]. The accessible frequency spectrum is not enough for the actual demand for transmission resources, and manage spectrum is still a revolutionary need by regulators [6].…”

Abstract-Spectrum sharing analysis is remarkably important in investigating the possibility for coexistence between IMT-Advanced system and existing wireless services when operating in the same or adjacent frequency channel. The frequency band, 470-862 MHz, is currently allocating to TV broadcasting services (TVBS) and subbands within it are also allocated to fixed wireless access (FWA) service. Recently, international telecommunication union-radio (ITU-R) sector has allocated sub-bands within 470-862 MHz for IMTAdvanced systems. This concurrent operation causes destructive interference that influences the coexisting feasibility between IMTAdvanced and these existing services, FWA and broadcasting. This paper addresses a timely and topical problem dealing with spectrum sharing and coexistence between IMT-Advanced systems and both FWA and TVBS within 790-862 MHz. Co-channel and adjacent channel with an overlapping band and with or without guard band are intersystem interference scenarios investigated. The deterministic analysis is carried out by spectral emission mask (SEM) technique as well as interference to noise ratio graph. Various significant factors such as channel width, propagation path lengths, environments losses, and additional losses due to antenna discrimination which influence the feasibility of coexistence are evaluated. Feasible coexistence coordination procedures in terms of carrier frequency offset, separation
