    The authors analyse an output queueing ATM switch which has the bandwidth-oriented priority (BOP) Markovian service scheme under the condition of heterogeneous traffic and multiple QoS. By designing the output queue service scheme in which heterogeneous traffic classes are separated by using separate buffers and the service to each buffer is done according to the BOP Markovian polling scheme, the ...

  • Performance, interarrival, and correlation analysis of four-phase MMPP model in ATM-based B-ISDN

    Publication Year: 1996, Page(s):363 - 368

    The MMPP has been used to model various B-ISDN sources, such as voice and video, as well as characterising the superposed traffic. It is able to capture the time-varying arrival rates and correlations between the interarrival times. This model is analytically tractable and produces accurate results. The matrix performance analysis of the continuous four-phase MMPP/D/1 queue proved that this queue ... View full abstract»

    The performance of digital and analogue direct-detection optical receivers with space diversity reception is analysed. The cumulative probability distribution of the received signal is calculated for M-branch diversity and equal-gain combining receivers. For a given probability of detection, the permissible threshold detection level is shown to increase with the number of diversity branches. The i... View full abstract»

  • Nonlinear dynamics in telecommunication systems: complex behaviour in nonlinear processing systems

    Publication Year: 1996, Page(s):347 - 355
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1024 KB)

    Nonlinear dynamic techniques are used to create a theoretical framework, from which the development, analysis and evaluation of a nonlinear model of a generalised switching element in a telecommunications network is investigated. The model represents the data flow through nonpreemptive multiprocess data processor systems found in communication nodes. A numerical solution to the model is presented,... View full abstract»

  • Reliability-throughput: optimisation for adaptive forward error correction systems

    Publication Year: 1996, Page(s):341 - 346
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (568 KB)

    Adaptive error control systems are very efficient for digital transmission over time-varying channels. An adaptive forward error correction system based on code selection is considered. An estimation of the channel quality is utilised by the transmitter to adaptively encode the information bits to be sent over the channel. The proper code is selected to optimise the system performance in terms of ... View full abstract»

  • Noncoherent detection with Viterbi decoding for GMSK signals

    Publication Year: 1996, Page(s):373 - 379
    Cited by:  Papers (11)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (704 KB)

    Noncoherent detection with Viterbi decoding is proposed for the detection of GMSK signals in a Gaussian channel. Two detection techniques, limiter discriminator detection and differential phase detection, are considered with Viterbi decoding. The numerical results show that the proposed receivers with Viterbi decoding perform significantly better than the known receivers with feedback, and the imp... View full abstract»

  • Optimal blocked random access algorithm for CDMA-random access systems

    Publication Year: 1996, Page(s):396 - 400
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (500 KB)

    Code-division multiple-access-random access systems are considered. Specifically, the authors consider a generalised common receiver model with transmitter-based code assignment and study a class of random access algorithms known as blocked random access algorithms. It is assumed that the number of active users at the beginning of a collision resolution epoch is known. An appropriate state of the ... View full abstract»

  • Cellular CDMA overlay systems

    In the past decade, there has been a considerable interest in spread spectrum techniques for applications that involve either code division multiple access (CDMA) or narrowband interference suppression. The CDMA network is considered to share a common spectrum with a strong narrowband microwave user. An interference suppression filter at each CDMA receiver is employed to reject the narrowband wave... View full abstract»

  • Iterative interference cancellation for FFH/MFSK MA systems

    Publication Year: 1996, Page(s):380 - 388

    Iterative interference cancellation is introduced to improve the spectral efficiency in fast frequency hopping multiple access systems. The proposed algorithm iteratively cancels interference from users whose symbols have already been estimated. Both an interference-only channel and a frequency selective fading channel are considered. Noncoherently detected M-ary frequency shift keying is employed... View full abstract»
