    This paper extends a simple mathematical treatment of the problem of cochannel interference in land mobile radio presented earlier, in which the interdependence between frequency reuse distance and required protection ratio was developed. By considering realistic patterns of frequency assignment, it is demonstrated that, for a given grade of service, spectrum economy is a discontinuous function of... View full abstract»

  • Design and performance evaluation of a 256-point adaptive filter

    Publication Year: 1980, Page(s):179 - 184

    In this paper an analogue c.c.d./m.o.s. implementation of an adaptive filter having high bandwidth and a large time-bandwidth product is described. The system demonstrates greatly improved performance characteristics in terms of size, power consumption, ease of use and increased bandwidth over previously published designs. Such a processor has many potential applications in communications signal p... View full abstract»

  • Masking ciphers

    This paper presents results on error probability as related to ciphertext length for masking ciphers. It also estimates minimum ciphertext length for unique decipherment. Two decipherment techniques have been presented. Our analysis indicates that masking ciphers are generally less effective than block ciphers. View full abstract»

  • Survey of radar data-processing techniques in air-traffic-control and surveillance systems

    Publication Year: 1980, Page(s):190 - 204
    Cited by:  Papers (9)

    The application of data-filtering techniques for air-traffic-control and surveillance systems is re-reviewed. Operational requirements of these systems are primarily described. They are typically composed of radars (mechanical scanning and phased array), data-processing devices (digital computers) and displays. The environment is determined by the number and characteristics of targets and by the d... View full abstract»

  • Predictors for intraframe encoding of Pal picture signals

    Publication Year: 1980, Page(s):205 - 211

    A predictor based on three previous `pels¿¿ along a scan line is examined for d.p.c.m. encoding of composite Pal signals. The predictor coefficients are described in terms of the ratio of sampling frequency fs to colour subcarrier fsc. Predictions based on p.e.l.s on the second previous and previous lines are derived for the case of fs/fsc = 2.5. Simple 2-dimensional predictors are then formed and... View full abstract»

  • Medium fading of radar targets at sea with special reference to operation at 3 cm and 10 cm

    Publication Year: 1980, Page(s):212 - 224
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1480 KB)

    At sea and in fair weather, the choice of operating wavelength for search radars for the detection of surface targets is largely influenced by the required angular resolution and maximum aerial aperture allowed. However, in considering maximum detection ranges in excess of 15 n miles, attenuation through very heavy precipitation favours a lower wavelength of the order of 10 cm, although angular re...

  • Log-Weibull distributed sea clutter

    Sea clutter was measured using and L-band long-range air-route surveillance radar (a.r.s.r.) at very low grazing angles between 0.13¿¿ and 0.25¿¿. From the stored data of six scans, it is shown that the sea-clutter amplitude statistics obey a log-Weibull distribution. View full abstract»

  • Numerical evaluation of the nonperiodic autocorrelation parameter for optimal phases of maximal length sequences

    Numerical results on the nonperiodic autocorrelation parameter important in phase-coded direct-sequence spread-spectrum communication is given. Optimal phases with respect to autocorrelation for all maximal-length sequences of periods 31, 63, 127, 255, 511, 1023, 2047 and 4095 are obtained. View full abstract»
