    Recent advances in technology have enabled a family ofsmall microwave satellite communication terminals to be constructed. This paper describes one of these, a prototype manpack equipment which can be carried by asingle person. It was completed in mid-1978 and has since been demonstrated on numerous occasions. Using a suitable satellite, such equipment can be usedto establish a link with a main SA... View full abstract»

  • The design and performance of transversal filters for the sidelobe reduction of pulses compressed from combined Barker phase codes

    Publication Year: 1981, Page(s):272 - 280

    The high temporal sidelobes of compressed combined Barker codes can be reduced using minimum-square-error transversal spiking filters. Very large (40 to 60 dB) peakto sidelobe ratios may be obtained for words up to 169 bits long using transversal filters which are only several hundred bits long. The effect of a Doppler frequency shift of the signal is analysed and a cross-ambiguity diagram is pres... View full abstract»

    Multipliers of two delta-sigma sequences are proposed in this paper. These multipliers are very simple in circuitry and provide the product in delta-sigma sequence form, permitting simple further processing. The multipliers were constructed and their performance was experimentally measured. It was found that a certain type of multiplier with a relatively simple circuitry, provides a high signal to...

  • A flexible microwave automatic network analyser system

    Publication Year: 1981, Page(s):287 - 298
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (3107 KB)

    This paper describes the microwave automatic network analyser system which has been established at the University of Warwick over the last decade. The different systems of correction which have been utilized are explained in detail, followed by an account of the system development, interfacing units and some new calibration test pieces. A description of the software precedes an outline of various ... View full abstract»

  • Bit-slice microprocessors in h.f. digital communications

    Publication Year: 1981, Page(s):299 - 301
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (367 KB)

    A 2.4 kbit/s baseband modem is being designed for use at h.f., incorporating modulation/demodulation techniques that are matched to those frequencies and the problems associated with them. Fed by a continuous serial datastream, the modulator functions are implemented wholly by a bit-slice microprocessor, and controlled by another more conventional microprocessor. Analogue output waveforms are gene... View full abstract»
