    Digital microwave radio communication offers high-fidelity transmission but it is susceptible to multipath propagation effects. The authors distinguish between the minimum phase and nonminimum phase fade types and present simulations illustrating typical radio performance during fades, before introducing various adaptive filter designs for implementing the equaliser to compensate for these two fad...

    The authors describe the ongoing research at the University of Bristol to explore mobile robot road-following algorithms and suitable hardware architectures to run these algorithms. The prototype hardware, designed and built at the University, is a real-time frame grabber system based on transputers. Two approaches to real-time road edge following that have been tested to guide a small tracked veh... View full abstract»

    The specification and standardisation of communication protocols has a significant commercial impact on users and so there is considerable international collaboration to provide new technologies and networks that will evolve to replace the current networks. The author reviews the ways in which this specification and standardisation is being applied to the protocols which support the current and fu... View full abstract»

    The D-MAC/packet system has been adopted as the signal format which offers a reception option involving a relatively inexpensive set-top convertor and yet it also provides a number of important options for enhancing the service. The authors briefly describe the D-MAC transmission system and highlight in particular how it can provide an evolution to high-definition television (HDTV) in the future View full abstract»
