  • Khatun, Sabira.; Saeed, Rashid A.; Abdullah, Mohd. Khazani.; Ali, Borhanuddin Mohd. (2007-03-12)
    Very high data rate packet systems, such as those based on ultra-wideband (UWB) signaling, face an increasingly important challenge – UWB radio uses sub-nanosecond pulses to transmit information, resulting is high resolution ...
  • Roviras, Daniel.; Carey, Daniel.; Senadji, Bouchra. (2007-03-12)
    A new technique is proposed that offers significant reduction of multiple access interference (MAI) encountered in asynchronous multicarrier code division multiple access (MC-CD MA) detection. Using a dual frequency switching ...
  • 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 ...
  • Chun, Hong.; Zhi-feng, Zhong.; Rui, Wu.; Bi-yang, Wen. (2007-03-12)
    Since the performance of high-resolution direction finding algorithm for HF Ground Wave Radar (GWR) is severely degraded by sensor phase and amplitude errors, the radar system's phase calibration is the prerequisite of ...
  • Shi, Jinglin.; Sun, Yi Sun.; Fang, Gengfa. (2007-03-12)
    Traditional way to implement VoIP application on hard-wired network is based on the fixed and invariable IP addresses of the source and destination nodes. However, in Mobile Ad-hoc Network (MANET), the IP address of each ...
  • Anh, Huynh Trong; Kim, Jinsang; Cho, Won-Kyung; Choi, Jongchan; Lim, Kitaek; Kwak, Jaemin (2007-03-12)
    In this paper, a robust, low-complexity timing synchronization algorithm suitable for 5.9 GHz Dedicated Short Range Communications (DSRC) system is proposed. The proposed method uses cross-correlation technique to detect ...
  • Salami, Oladayo.; Chan, H. Anthony. (2007-03-12)
    Output Queuing (OQ) and Input Queuing (IQ) are the two basic queuing strategies implemented in routers. IQ has been identified as the simplest and the most scalable. However, IQ achieves only 58.6% throughput due to the ...
  • So, Joseph Yick Hon.; Wang, Jidong. (2007-03-12)
    Mobile IP allows the mobile node roaming into a new IP network without losing its connection with its peer. Mobile IPv6 is using Mobile IP with Route Optimizationto improve performance by avoiding the triangle routing and ...
  • Deshpande, Vivek S. (2007-03-12)
    Mobile Ad-Hoc Networks (MANETs) are becoming increasingly popular as more and more mobile devices find their way to the public, besides traditional" uses such as military battlefields and disaster situations they are being ...
  • Berber, Stevan M.; Jovic, Branislav. (2007-03-12)
    A mathematical model of a synchronization block of a DS-CDMA system is developed and then investigated using a simulation. For this synchronization a pilot sequence has been used that can be a pseudorandom sequence or a ...
  • Chang, Jau-Yang.; Chen, Hsing-Lung. (2007-03-12)
    Multimedia applications (audio phone, video on demand, video conference, file transfer, etc.) will be integrated into future mobile communication systems. Bandwidth is the most critical resource in mobile multimedia wireless ...
  • Bacha, Mansour.; Djebouri, Djamel.; Kameche, Mohamed. (2007-03-12)
    This paper discusses the simulation and the design of an RF transmitter for small satellites operating in the commercial S- band (2.2 - 2.29 GHz) with a data rate of 8Mbps. In such systems, modelling frequency-dependent ...
  • 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 ...
  • Sithamparanathan Kandeepan (2007-03-12)
    The study of phase locked loops (PLL) has been heavily treated in literature and most of the theoretical and the analytical results of such are verified using simulations. Here we provide a real-time implementation of a ...
  • Li, Xuan.; Senadji, Bouchra. (2007-03-12)
    Two major sources of interference affect asynchronous MC-CDMA systems, i.e. multiple access interference due to subcarriers with the same frequency (MAI) and multiple access interference due to subcarriers with different ...
  • Chicharo, Joe.; Dutkiewicz, Eryk.; Tran, Le Chung.; Huang, Xiaojing. (2007-03-12)
    In this paper, we expand the idea of spreading the transmitted symbols in OFDM systems by unitary spreading matrices based on the rotated Hadamard or rotated Discrete Fourier Transform (DFT) matrices proposed in the ...
  • Zhu, Yaolin.; Li, Changyi.; Zheng, Guoxin. (2007-03-12)
    In this paper, the channel estimation techniques for multiband (MB) OFDM ultra-wideband (UWB) wireless communications are investigated. By combining orthogonal frequency-division multiplexing (OFDM) with multi-band, the ...
