In this paper, the performance of serial concatenated space-time code (SCSTC) in an OFDM system has been investigated over frequency-selective fading channel. Time variation of the channel leads to interchannel interference (ICI), which degrades the bit error rate (BER) performance of the system. The degradation depends on the maximum Doppler shift and flat fading channel, the performance with OFDM over frequency selective fading channel partly depends on the channel delay profile. It can be seen that the highest possible diversity gain is the product of the number of transmit antennas and the number of delay diversity order. Finally, simulation results have been evaluated for quasi-static frequency-selective fading channel.

This paper presents the design of new optical ATM switches that use code-division multiple access (CDMA) and strict optical orthogonal codes (OOCs). The cross-correlation and autocorrelation constraints (i.e. /spl lambda//sub c/ and /spl lambda//sub a/) of strict OOCs are always limited to be "1" for incoherent optical processing, regardless of whether an aperiodic or a periodic pulse sequence is input to optical CDMA decoders. Since the coding and correlation of strict OOCs are performed in the optical domain, the processing speed of the proposed ATM switches can be very high. This can support real-time broadband communications. Moreover, the proposed ATM switch can flexibly handle both equal-rate and variable-rate communication services without violating /spl lambda//sub c/=/spl lambda//sub a/=1 and without any change of the optical CDMA encoders/decoders. In so doing, it can substantially improve the switch flexibility without increasing the system's complexity.

Kwong Lian-Kuan Chen Kwok-Wai Cheung Telecommunications Program School of Advanced Technologies Asian Institute of Technology Bangkok Thailand Department of Engineering Hofstra University Hempstead NY USA Department of Information Engineering Chinese University of Hong Kong New Territories Hong Kong China

We propose a feasible architecture to implement tunable all-optical synchronous CDMA networks. Such a network is simply based on single rapidly tunable optical delay-lines and requires only a small number of electro-optic switches. Fast coding and decoding algorithms for synchronous prime-sequence codes are described. By using the proposed technique, all-optical synchronous CDMA networks can be constructed by integrated optics and can achieve a very high processing speed.

Floor plan construction is the basis for fingerprint-based localization and people's activity learning, especially in the environments where the geometrical map is not available or does not exist. To this end, we propose a new received signal strength (RSS) fragment matching approach to identify the location points (LPs) in floor plan as the overlapped pieces between the fragments. Then, by means of the Smith-Waterman alignment, each LP can be recognized as a winning path in scoring space. Finally, we use the Allen's interval algebra to assemble the time-stamped LPs into a floor plan in target area. The experiments with the actual Wi-Fi RSS measurements recorded in HKUST campus demonstrate that our proposed approach performs better than the conventional K-means clustering and spectral clustering in floor plan construction. © 2014 ICIC International.

Humans rely increasingly on sensors to address grand challenges and to improve quality of life in the era of digitalization and big data. For ubiquitous sensing, flexible sensors are developed to overcome the limitations of conventional rigid counterparts. Despite rapid advancement in bench-side research over the last decade, the market adoption of flexible sensors remains limited. To ease and to expedite their deployment, here, we identify bottlenecks hindering the maturation of flexible sensors and propose promising solutions. We first analyze continued...challenges in achieving satisfactory sensing performance for real-world applications and then summarize issues in compatible sensor-biology interfaces, followed by brief discussions on powering and connecting sensor networks. Issues en route to commercialization and for sustainable growth of the sector are also analyzed, highlighting environmental concerns and emphasizing nontechnical issues such as business, regulatory, and ethical considerations. Additionally, we look at future intelligent flexible sensors. In proposing a comprehensive roadmap, we hope to steer research efforts towards common goals and to guide coordinated development strategies from disparate communities. Through such collaborative

作者： Hyenyoung Yoon Junseok Hwang Martin B. H. Weiss Technology Management Economics and Policy Program College of Engineering Seoul National University Seoul South Korea Department of Information Science and Telecommunications School of Information Sciences University of Pittsburgh Pittsburgh PA USA

Due to the increase of spectrum demand, the value of spectrum resource has been increased and efficiency of spectrum usage has been important issues in the wireless industry. Therefore recently, there have been many efforts on changing spectrum management framework based on the market mechanism. This research analyzes three different mechanisms as an alternative of secondary trading framework; a brokerage mechanism, auctions and a direct trading. As a consequence, this research suggests an optimal framework for the secondary use trading based on the in-depth simulations which consider different attributes by technical characteristics and market changes and investigate economic values and competition environments.
