    For Dick Tracy of comic-strip fame and Captain Kirk of `Star Trek¿, voice communication from tiny equipment over vast distances posed no problem, but in the real world of 1986 the situation is much more difficult. Historically, mobile telephone systems using HF, VHF and UHF radio have been developed since the Second World War with military and commercial systems evolving in parallel. Although oft...

  • Effect of sampling offset on Pe performance of partial response systems

    Publication Year: 1987
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (381 KB)

    The paper applies the Gram-Charlier series method to the calculation of the probability of error Pe of partial response (PR) systems. This method allows the exact calculation of error probability including the effects of sampling off-set and additive Gaussian noise. Five classes of precoded PR systems are considered. The results obtained in the method are compared with those obtained with Chernoff... View full abstract»

  • Pseudoternary partial response FSK

    Publication Year: 1987, Page(s):13 - 19
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (615 KB)

    We show how to compute the error probability of frequency-shift keying with limiter-discriminator-integrator detection in the presence of narrowband filters in the transmitter and receiver when the symbols are pseudoternary, i.e. they are generated from binary symbols using duobinary, modified duobinary and dicode rules. We show numerical results assuming a Butterworth filter in the receiver with ... View full abstract»

  • Error rate prediction for NCFSK digital mobile radio systems

    Publication Year: 1987, Page(s):21 - 26
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (702 KB)

    Error performance analysis for the VHF digital mobile radio system is presented. The binary frequency-shift keying (FSK) system using noncoherent (NC) demodulation, with a limiter/discriminator receiver, is considered. All major error-causing factors, such as signal fading, Gaussian and impulsive noise, are taken into account and the corresponding general expression for the error probability is de...

  • Postdetection diversity using a modified phase-correction loop for digital land mobile radio

    Publication Year: 1987, Page(s):27 - 34
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (800 KB)

    A postdetection diversity system using a phase-correction loop modified by the inclusion of a differential demodulator (DD) or a frequency demodulator (FD) is described. Binary and quaternary digital modulation for DPSK and digital FM are considered. An analysis considering additive Gaussian noise shows that, although the diversity combiner proposed is inherently the postdetection type, the well k... View full abstract»

  • Log-normal clutter cancellation

    Publication Year: 1987, Page(s):35 - 42
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (712 KB)

    The problem of clutter cancellation in a non-Gaussian environment is becoming more and more important in modern high-resolution radars, owing to uncertain clutter statistics. To evaluate the MTI canceller performances, in the paper we examine an intermediate frequency model which gives, in the video frequency, a signal with log-normal (LN) probability density function (PDF). The improvement factor... View full abstract»

  • Rotationally invariant coded PSK signals

    Publication Year: 1987, Page(s):43 - 52
    Cited by:  Papers (4)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1320 KB)

    The paper describes the design of eight new rotationally invariant rate-2/3 and rate-3/4 convolutional codes. The rate-2/3 codes are suitable for 8PSK (8-level PSK) coded signals and are transparent to phase rotations in the received signal carrier phase, that are multiples of ¿¿/2 radians, whereas the rate-3/4 codes are suitable for 16PSK (16-level PSK) coded signals and are transparent to phase ...

  • Angular superresolution with phased array radar: a review of algorithms and operational constraints

    Publication Year: 1987, Page(s):53 - 59
    Cited by:  Papers (4)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1161 KB)

    A number of methods have been suggested to improve spectral or angular resolution. These methods have arisen from quite different fields of application, and are difficult to compare. The paper collects aspects for the application of such methods to the case of angular resolution with a phased array radar. We list the main methods and their properties, and point out constraints for a real radar app... View full abstract»

  • Power spectra of CPFSK waveforms, having nonuniform input PDFs

    Publication Year: 1987, Page(s):61 - 68
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (622 KB)

    Power spectral density (PSD) analysis is often undertaken assuming equally likely signalling input levels, and hence the different criteria of performance are evaluated with this condition in mind. In practice, however, cases of unequal probabilities of signalling input do arise due to choice of coder, and the study of these conditions is important. Power spectral densities are sensitive to variat... View full abstract»

  • Analysis of transient data in noise

    Publication Year: 1987, Page(s):69 - 78
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1013 KB)

    A linear prediction method for accurately estimating the parameters of a rational model of transient-type data is presented. This method makes use of the singular value decomposition of an extended-order autocorrelation-like matrix estimate associated with the time series being analysed. The method is first tested on simulated data consisting of three exponentially damped sinusoids of closely spac... View full abstract»

  • Performance evaluation of packet-switched networks with retransmission due to finite buffers and channel errors

    Publication Year: 1987, Page(s):79 - 84
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (759 KB)

    The equilibrium behaviour of store-and-forward packet-switched networks is studied under realistic conditions via a network of queues. A network with a general mesh topology is considered. Switching nodes have a finite number of store-and-forward buffers, and communication channels are not perfect. A node-node protocol with positive acknowledgment and retransmission is modelled, and consumes part ... View full abstract»

  • Multiple criteria for hand-off in cellular mobile radio

    Publication Year: 1987, Page(s):85 - 88
    Cited by:  Papers (2)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (542 KB)

    A cellular hand-off treatment based on cell membership degrees is presented. The proposed method permits the systematic incorporation of a variety of different weight criteria. An example of application is given, and it is shown that the procedure leads to a low number of handoffs without excessive cell coverage overlapping. If one of the criteria is derived from traffic levels, then traffic imbal... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (826 KB)

    The paper presents a new solution to the combinatorial problems that arise when multiple targets are to be tracked simultaneously. In multitarget situations, the correspondence between targets and observations may be lost because of crossing trajectories, close-by targets, false alarms, missed detections etc. The number of data association hypotheses that are feasible and for which probabilities h...
