  • Analysis of banyan networks offered traffic with geometrically distributed message lengths

    Publication Year: 1995, Page(s):285 - 291
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (596 KB)

    An analysis of finite-input-buffered banyan networks offered traffic having geometrically distributed message lengths is presented. This is one of the few multistage-network analyses for networks offered non-unit-length messages and is the only one that the authors are aware of for finite-input-buffered banyan networks. In the analysis, network switching elements are modelled using two state machi... View full abstract»

  • Autocorrelation of Golomb sequences

    Golomb sequences form a class of polyphase sequences which have perfect periodic autocorrelation. Given certain constraints, they also have favourable aperiodic autocorrelation. The paper presents a comprehensive study of the asymptotic behaviour of the aperiodic autocorrelation function of Golomb sequences. Some bounds for this function are obtained View full abstract»

    Two 8-state rate 5/6 2×8PSK TCM designed for very small-aperture-terminal (VSAT) Gaussian and fading channels (GTC and FTC systems), and eventually a system with optimum performance over the mobile-satellite (MSAT) fading channel (OFT system) is obtained. The operation of these coded systems is compared with uncoded systems over Gaussian and shadowed Rician fading channels by computer simula... View full abstract»

  • Demodulation and decoding for diversity mobile radio systems

    In mobile communication systems, channel coding and equalisation are required to achieve high-quality signals. The channel degradation owing to multipath fading, time spread and Doppler spread can be further reduced by using diversity techniques, where the receiver is provided with multiple independently faded replicas of the same information signal. The information coming from the diversity chann... View full abstract»

  • Bit-error probability of QPSK with noisy phase reference

    Publication Year: 1995, Page(s):292 - 296

    An approximate result is obtained for the bit-error probability of quadriphase shift keying in the presence of additive white Gaussian noise and a Tikhonov distributed-phase-reference error. The accuracy of the approximation is verified via actual numerical integration of the bit-error-probability formula. The approximation is easy to compute, and shows correctly the behaviour of the bit-error pro... View full abstract»

  • Overlapping coverage and channel rearrangement in microcellular communication systems

    Publication Year: 1995, Page(s):323 - 332
    Cited by:  Papers (23)

    Overlapping coverage areas of nearby base stations arise naturally in cellular communication systems, especially in small-cell capacity microcellular configurations. With overlap, some users may have access to channels at more than one base station. This enhanced access can be used to improve teletraffic performance characteristics. This issue is considered for cellular systems, in which hand-off ... View full abstract»

  • Analytical and measured performance of the combined analogue locked loop universal modulator (CALLUM)

    Publication Year: 1995, Page(s):297 - 306
    Cited by:  Papers (4)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (672 KB)

    A novel technique for achieving very high efficiency frequency translation and RF amplification is described, termed the combined analogue locked loop universal modulator (CALLUM). Analytical, simulation and measured results for the system are presented which demonstrate the performance bounds of the CALLUM technique and demonstrate its application in portable radio designs for current and future ...

  • Bit-error-rate performance for asynchronous DS-CDMA over multipath fading channels

    Publication Year: 1995, Page(s):307 - 314

    The authors analyse the performance of uncoded and coded asynchronous DS-CDMA systems over multipath fading channels. The fading-channel model adopted is a general one; by varying the parameters it is possible to model Rician or Rayleigh fading. Using these fading models, the authors developed the probability of bit error for the asynchronous DS-CDMA by modelling the multiple access interference (... View full abstract»
