  • Yu, Limin; White, Langford B. (2007-03-12)
    In this paper, we present the design of complex Ultra-wideband (UWB) pulses which enables the phase-shift keying (PSK) modulation for UWB Impulse Radio (IR) Communications. Two classes of complex UWB pulses are proposed ...
  • Simic, Ljiljana.; Berber, Stevan M. (2007-03-12)
    This paper presents the implementation of a multi-user chaos-based communication system in DSP. The system is based on the chaotic phase shift keying (CPSK) digital modulation scheme, where chaotic signals are used as the ...
  • Joarder, Shamim A; Jayasuriya, Aruna; Perreau, Sylvie; Burachik, Regina (2007-03-12)
    This paper addresses the impact of the spreading gain on the efficiency of mobile Ad Hoc networks using Code Division Multiple Access (CDMA) as a mode of transmission. In particular, we concentrate on the trade off between ...
  • Lal, Sara.; Bekiaris, Evangelos. (2007-03-12)
    To date no-study has tested the reproducibility of electroencephalography (EEG) changes that occur during driver fatigue. For the EEG changes to be useful in the development of a fatigue sensing and countermeasure device ...
  • Postula, Adam.; Bialkowski, Marek E.; Bialkowski, Konstanty S.; Uthansakul, Peerapong. (2007-03-12)
    This paper describes the design of a Multiple Input Multiple Output testbed for assessing various MIMO transmission schemes in rich scattering indoor environments. In the undertaken design, a Field Programmable Gate Array ...
  • Patachaianand, Rachod.; Sandrasegaran, Kumbesan. (2007-03-12)
    Wideband Code Division Multiple Access (WCDMA) is the multiple access technique used in the third generation of mobile telecommunication (3G) systems. Capacity of this technique does not have an exact limit. The maximum ...
  • Lowe, Darryn.; Raad, Ibrahim S.; Huang, Xiaojing. (2007-03-12)
    This paper presents the study undertaken with block spread OFDM and compares three spreading matrices. The matrices include the Hadamard, Rotated Hadamard and Mutually Orthogonal Complementary Sets of Sequences (MOCSS). ...
  • Harrison, Jeffrey.; Burnet, Craig.; Cowley, William.; Boers, Michael.; Hall, Leonard.; Holland, Ian.; Howarth, James.; Batty, Mike.; Weste, Neil.; Abbott, Derek.; Zhu, Yingbo.; Davis, Linda M.; Parker, Anthony. (2007-03-12)
    ISM spectrum at 60GHz has attracted attention for possible high-speed applications in wireless communications for well over ten years. However, no high volume applications have emerged. Despite progress in mm-wave ICs, the ...
  • Lang, Stephan; Daneshrad, Babak (2007-03-12)
    This paper describes the development of a very flexible multi-antenna testbed built on 5 PCBs. The FOM testbed (FOM, Flyable OFDM MIMO) was built with off-the-shelf components and can be configured with any number of ...
  • Muntean, Cristina Hava; Muntean, Gabriel-Miro (2007-03-12)
    As wireless technologies are competing with wired solutions in delivering information, there is a clear shift of e-learning towards mobile learning (m-learning). M-learning, which involves both wireless communications and ...
  • Achieng, Robert; Chan, H. Anthony (2007-03-12)
    There will be heterogeneous wireless access networks in 4G systems, e.g., WLAN, UTRAN etc. The networks will need to support QoS provisioning and full mobility. For each connection request by a mobile user in such networks, ...
  • Soudani, Nabila.; Bouallegue, Ridha. (2007-03-12)
    Multicarrier (MC) systems, such as OFDMA (Orthogonal Frequency Division Multiple Access), which are quite developed in the literature, were shown to be the adequate solution for multipath transmission. However, even with ...
  • Lensson, E. S.; Hose, C. R.; Kerans, A. J. (2007-03-12)
    The already intensive use of the radiofrequency spectrum for wireless communication systems continues to increase. The success of wireless communications and the integral part they now play in our modern society is, in ...
  • Nkansah-Gyekye, Yaw.; Agbinya, Johnson I. (2007-03-12)
    This paper reports on the design and implementation of multi-criteria vertical handoff decision algorithms in a heterogeneous wireless wide area network (WWAN) and a wireless local area network (WLAN) environment. An ...
  • Kogeda, Okuthe P.; Agbinya, Johnson I. (2007-03-12)
    Cellular network service providers compete with each other for the vast and dynamic market that is characterized by the ever-changing services on offer and technology. These services require very reliable net-works that ...
  • Abduljalil, Fekri M. A.; Bodhe, Shrikant. K. (2007-03-12)
    Handoff performance is one of the important metrics in mobility management where frequent handoff can occur in single session and that may degrade the performance of TCP (Transmission Control Protocol) and UDP (User Datagram ...
  • Wilson, Carol (2007-03-12)
    With the growth of wireless technology for an ever-increasing range of devices, services, applications and users, the role of spectrum management is becoming more complex and difficult. National and international spectrum ...
  • Shi, Jinglin.; Dutkiewicz, Eryk.; Fang, Gengfa. (2007-03-12)
