    The greater-of (GO) constant false alarm rate (CFAR) detector selects the greater of the leading and lagging sets of the reference noise cells to minimise the effect of clutter and jamming. The performance of the GO detector is derived for the case where an arbitrary number of interfering targets are present in the leading and lagging reference noise cells. To improve its performance in this situa... View full abstract»

  • Performance analysis of GMSK frequency detection with decision feedback equalisation in digital land mobile radio

    The bit-error-rate (BER) performance of premodulation Gaussian filtered MSK (GMSK) using frequency detection (FD) in conjunction with 1 bit decision feedback equalisation (DFE) is theoretically investigated. The introduction of the premodulation filter causes severe intersymbol interference (ISI) in the waveform of the input to the FM modulator. DFE is used for reducing the ISI effect and therefor...

  • Outage probability calculations for multiple cochannel interferers in cellular mobile radio systems

    Publication Year: 1988, Page(s):208 - 215
    Cited by:  Papers (30)

    The calculation of outage probability is discussed in relation to cochannel interference problems inherent in mature cellular radio systems. Outage probability equations for coverage only and for single cochannel interferer situations are reviewed briefly, and examples of the application of these results to the estimation of the service area of a typical cellular base station are given. An analyti... View full abstract»

  • Theoretical performance prediction of the MUSIC algorithm

    Publication Year: 1988, Page(s):216 - 224
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (913 KB)

    The expected value of the MUSIC `spectrum¿ is investigated for two situations. First we investigate the case when there are very few data samples available. The paper performs a second-order perturbation analysis, using the assumption that the data comes from a complex Gaussian distribution. The final expression which is obtained is shown to be very simple to compute, and gives very good agreemen... View full abstract»

  • Cochannel interference between point-to-point urban microwave radio systems

    Publication Year: 1988, Page(s):225 - 232
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (907 KB)

    Low-cost point-to-point radio systems are available at a number of frequencies in both the centimetre and millimetre wavebands for local business applications. In urban areas a high degree of cochannel operation is predicted, both for reasons of spectral efficiency, and because forecast demands greatly exceed the number of available channels. The paper presents an initial probabilistic study of th... View full abstract»

  • Effects of random sensor motion on bearing estimation by the MUSIC algorithm

    Publication Year: 1988, Page(s):233 - 250
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1993 KB)

    The MUSIC method of bearing estimation is a high resolution estimating method utilising the orthogonal relationship between the signal and noise subspaces which are spanned by the eigenvectors of the covariance or the crossspectral density matrices. In the application of the MUSIC method to bearing estimation in a sonar environment, an important source of error is that the positions of the array o... View full abstract»

  • New technique for speaker-independent isolated-word recognition

    Publication Year: 1988, Page(s):251 - 257

    In a speech recognition system based on dynamic time warping (DTW) the DTW operation is used to time-align two words while calculating the distance between them. The DTW operation is repeated many times as the number of the reference templates in the system. As a result the processing becomes time-consuming. We propose the generation of a single pattern to be used as a time aligning pattern (TAP) ... View full abstract»

  • Autocorrelation and power spectrum of Hadamard signalling

    Publication Year: 1988, Page(s):258 - 261
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (407 KB)

    The paper presents results for the autocorrelation and power spectrum of digital modulation for M-ary orthogonal and biorthogonal signal sets based on binary Hadamard matrices. Such signal sets provide easily-mechanised orthogonal (and related) constructions, and are important in coded signalling for jammed and/or fading channels using large-alphabet codes.

  • Transfer function parameters in multipath channel modelling

    Publication Year: 1988, Page(s):262 - 264
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (289 KB)

    Two alternative forms of representation of a multipath fading channel frequency response function are presented. Appropriate analytical expressions relating the two sets of characterisation parameters are derived. The results are applied to published data to illustrate their use. View full abstract»

  • Analytical expression for the performance bounds of 16-QAM signalling in non-Gaussian products environment

    Publication Year: 1988, Page(s):265 - 271

    The error performance of 16-QAM schemes operating in nonlinear satellite channels where additive white Gaussian noise (AWGN) appears on the down link has already been evaluated. However, it is well known that in realistic nonlinear satellite transmission systems, additive channel noise apppears on both the up- and the downlink; and indeed it is mostly the presence of uplink Gaussian channel noise ...

  • Class of optimum signal shapes in data transmission

    Publication Year: 1988, Page(s):272 - 276
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (558 KB)

    An efficient method is given for the optimal design of band-limited, Nyquist-type signal shapes for data transmission, which maximises its energy in a time interval and which generates no intersymbol interference at the periodic sampling instants. The computation is straightforward and the constraint for intersymbol interference is shown to be easy to include in the problem. A numerical example is... View full abstract»
