A Fittingness Factor-Based Spectrum Management Framework for Cognitive Radio Networks

In order to increase cognitive radios (CRs) operation efficiency, there has been an increasing interest in strengthening awareness level about spectrum utilisation. In this respect, this paper proposes to exploit the fittingness factor concept to capture the suitability of spectral resources exhibiting time-varying characteristics to support a set of heterogeneous CR applications. First, a new knowledge management functional architecture for optimizing spectrum management has been constructed. It integrates a set of advanced statistics capturing the influence of the dynamic radio environment on the fittingness factor. Then, a knowledge manager (KM) exploiting these statistics to monitor time-varying suitability of spectrum resources has been proposed to support the spectrum selection (SS) decision-making process. In particular, a new Fittingness Factor-based strategy combining two SS and spectrum mobility (SM) functionalities has been proposed, following either a greedy or a proactive approach. Results have shown that, with a proper fittingness factor function, the greedy approach efficiently exploits the KM support at low loads and the SM functionality at high loads to introduce significant gains in terms of the user dissatisfaction probability. The proactive approach has been shown to maintain the introduced performance gain while minimizing the signalling requirements in terms of spectrum handover rate.

Optical-transmission characteristics of optical-fiber cables and installed optical-fiber cable networks for WDM systems

Many cables containing 1.3-/spl mu/m zero-dispersion single-mode (SM) optical fibers are installed in trunk and access networks. Recently, there have been a number of studies on wavelength-division-multiplexing (WDM) systems designed to increase transmission capacity and flexibility. If we can construct WDM systems using SM optical-fiber cable networks designed to transmit using wavelengths in the 1.3-/spl mu/m window (O-band), this will prove very effective in reducing construction costs. It is therefore important to examine the wavelength dependence of the transmission characteristics of SM optical-fiber cables and networks that have already been installed and in which several optical fibers are joined. In this paper, we describe the measured optical characteristics of SM optical-fiber cables and installed optical-fiber cable networks at various wavelengths. The optical characteristics were stable in the 1.46 to 1.625-/spl mu/m wavelength range and we confirmed that the installed SM optical-fiber cable networks could be used for WDM system applications.     

Technological innovation systems and IT industry sustainability in China: A case study of mobile system innovation

In recent years China not only caught up with countries leading the field of wireless mobile technologies but has kept a pace following years of innovation, as mobile technologies like TD-SCDMA and TD-LTE in China have been recognized as international standards by the International Telecommunication Union (ITU). Through case studies of the technological innovation systems (TISs) of 3G (TD-SCDMA), 4G (TD-LTE) and 5G in China, this work advances our understanding of the relationship between technology innovation and TISs, as well as that between the TIS and industry sustainability in the IT field. An innovation system function-based framework is applied to structure the data collection and analyse the results. Extensive documentary research and semi-structured interviews are conducted in this study. The key point of the reasoned argument of our conclusion is that a well-functioned TIS not only facilitates technology development and diffusion, but also promotes the sustainability of the IT industry by pushing forward socio-technical transformation.     

Constellation design and performance analysis of the parallel spatial modulation

Spatial modulation (SM) is a relatively recent multiple‐input multiple‐output (MIMO) system in which information is carried by the index of the antenna used for transmission as well as by the conventional signal symbols. Several systems that build upon SM have since been proposed including the generalized SM (GSM), a variant of GSM with multiple active antennas (MA‐SM), quadrature SM (QSM), and parallel SM (PSM), among others. The PSM system can increase the spectral efficiency by splitting the antenna set into groups and applying SM independently in each group using the same signal symbol. In this paper, we first derive the upper bound on the error probability of the PSM. The search of the optimal constellation set is then formulated as a multi‐objective optimization problem, where the obtained constellation minimizes the asymptotic error probability. We conclude that as the number of antenna groups increases, the proposed constellation converges to the conventional phase‐shift keying at relatively low number of transmit antennas. The simulation results show that the proposed constellation outperforms conventional constellations by as much as 5 dB, for high‐modulation orders. Since the multi‐objective optimization is independent of the channel matrix, it can be easily done off‐line. This implies that these gains come at no complexity or delay cost.

Improving the Performance of Spatial Modulation Schemes for MIMO Channels

Spatial modulation (SM) is a recent MIMO transmission concept that holds the potential to increase the spectral efficiency over wireless links using low-complexity transceivers. In this paper, an overview and performance analysis on the key issues of this emerging technology is presented. Based on this analysis, a performance enhancement is suggested by introducing an improved spatial modulation (ISM) scheme that retains the SM key advantages. It is observed that transmitting the same data symbol from more than one antenna at a time has a positive effect in terms of spectral efficiency but, on the other hand, it degrades the bit error rate (BER) performance. In this sense, a more general SM mapping rule is introduced aiming to provide a criterion for choosing an effective performance/rate/complexity trade-off according to the system requirement. An upper bound on the BER performance for ISM is derived and compared to Monte Carlo simulation results. In addition, a two-stage adaptive detector is also presented to enhance further the performance/complexity trade-off at the receiver for SM-based techniques.     

An integrated adoption model for e-books in a mobile environment: Evidence from South Korea

This study examines what factors lead to the adoption of the mobile e-book in South Korea. For this purpose, this research integrated the diffusion of innovation theory and technology acceptance model with the model of innovation resistance and applied this integrated model to the context of mobile e-book adoption. An online survey was administrated, and the data collected were analyzed with the structural equation model (SEM). Research results showed that individual innovativeness has a significant influence on perceived usefulness and perceived ease of use. It also revealed that both of perceived usefulness and perceived ease of use affect not only intention to use but also the innovation resistance. The innovation resistance has significant negative influence on the intention to use. Perceived risk of mobile e-books increases innovation resistance in a positive way. The implications of these results are discussed.

Demand forecasting for the 5G service market considering consumer preference and purchase delay behavior

Unlike previous mobile communications technologies that centered on service subscribers, 5G mobile communication (5G) is expected to converge with various industry fields such as transportation, manufacturing, and construction, thereby stimulating innovation and generating significant ripple effects. At a time when 5G commercialization is incipient, it is necessary to understand mobile communication service users who are likely to be important initial users for the creation and diffusion of 5G services. The current study analyzed consumer preference for 5G services based on conjoint survey data and a mixed logit model, and we conducted a market simulation based on the estimation results to determine the impact of 5G technology development on the 5G market, specifically regarding the mobile communication fields. In addition, this study derived consumer purchase delay factors for 5G services using an ordered logit model. The results show that consumers delay the adoption of 5G services mainly because of the cost and lack of need. By considering the consumer purchase delay, it is estimated that the acceptance rate of 5G services by consumers will decrease by more than 50%; this is because it is hard to conclude a purchase delay of more than one year leads to an actual purchase. The results of this study suggest important strategic implications that are likely to reduce the purchase delay of consumers, improve the actual adoption rate, and increase the diffusion of 5G services.
