Astronomy at the infra-red wavelengths is a comparatively recent branch of the subject, having really only started circa 1970. Since that time it has grown enormously in scope and sensitivity. This paper reviews the techniques used and problems faced by the infra-red astronomer. The topics discussed include: ground based astronomy, single element detectors, array detectors, array electronics and c... View full abstract»

The worldwide interest in personal mobile satellite communications using constellations of low-orbiting satellites highlights the handset antenna as a component that has a critical effect on the overall system viability. The antenna design is, however, influenced by many factors and the purpose of this overview is to identify key design aspects, their interrelation and prospects for optimisation. ...

Location management in mobile communication systems is concerned with those network functions necessary to allow the users to be reached wherever they are in the network coverage area. The basic operations for that purpose-paging and location updating-are resource-consuming since both involve signalling over the radio link between the mobile stations and base stations. Future cellular mobile commu... View full abstract»

On-chip, non-volatile analogue memory is essential in hardware implementations of many of the early stages of signal processing, including neural network preprocessors and other adaptive sensor fusion amplifiers. Such storage is also desirable for trimming analogue circuits electronically and for parameter retention on power-down. This paper reviews the current state-of-the-art from a designer's p...
