  • Abhayapala, T.; Jayalath, D.; Yuan, X.; Zhang, J. (2007-03-12)
    In Cyclix Prefix OFDM (CP) systems, synchronization to the maximal multipath signal generally causes no problem, however, inter carrier interference (ICI) will be introduced in Zero-padding OFDM (ZP-OFDM) systems, e.g, ...
  • Zakarevicius, Ramutis A. (2007-03-12)
    The integrator technique of time delay measurement is revisited and its suitability to many aspects of ultra wideband (UWB) communications systems is indicated. In the paper basic properties of the integrator technique, ...
  • Vucetic, Branka.; Munasinghe, Kumudu S.; Jamalipour, Abbas. (2007-03-12)
    In this paper, a novel architecture for interworking of the Wireless Local Area Network (WLAN) and the Third Generation (3G) mobile cellular network is presented. This architecture is a hybrid model with additional controls ...
  • Sandhu, Gobindar S.; Berber, Stevan M. (2007-03-12)
    In this paper the results of investigating various orthogonal signals that can be used as the carriers of users' information in a multiuser communication system are presented, primarily chaotic signals, wavelets, human ...
  • Kao, Johnny W. H; Berber, Stevan M. (2007-03-12)
    This paper outlines a novel iterative decoding technique for a rate K/N convolutional code based on recurrent neural network (RNN) with stopping criterion. The algorithm is introduced by describing the theoretical models ...
  • 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 ...
  • Humaira Haffajee.; Chan, H Anthony. (2007-03-12)
    The WLAN and WiMAX standards are candidate solutions for a low-cost broadband wireless network. Interworking the two networks, using the network-layer QoS mechanisms of the Next Generation Network, will allow them to ...
  • Van Schaik, André.; Dong, Xiao Feng.; Jin, Craig. (2007-03-12)
    A cascode LNA was optimized for a GPS receiver radio frequency front end using a 0.18 μm CMOS technology. By careful choice of device geometry, gate and source degeneration inductors, a fully integrated LNA can be optimized ...
  • Choi, Jinho.; Chee, Tommy K.; Lim, Cheng-Chew. (2007-03-12)
    This paper presents novel closed-form solutions to the sub-channel and power allocation problems of an orthogonal frequency division multiple access (OFDMA) system. We model the Rayleigh fading channel as a finite-state ...
  • Joel Sing.; Soh, Ben. (2007-03-12)
    Over the last several years digital pests - namely viruses and spam - have reached epidemic proportions, severely impacting the usability of digital communication systems, primarily affecting email. These pests result in ...
  • Murray, Boyd M; Reisenfeld, Sam (2007-03-12)
    We investigate the effects of quantization and AGC (Automatic Gain Control) in MIMO (Multiple Input Multiple Output) wireless systems. We derive the cutoff rate equations for a deterministic MIMO channel with quantization ...
  • Dissanayake, Tharaka; Esselle, Karu P. (2007-03-12)
    In UWB system design and optimization, antennas are usually represented by a single transfer function relating the input voltage to the radiated electric field in the free space. However, the transfer function of planar ...
