It is shown that for a broad class of random binary processes, the mean of a binary process, conditioned on its zero crossings, is proportional to the derivative of the correlation function of that process. This specific mean, referred to as the impl

A new, so-called chaotic pulse-sequence radar (CPSR) has been developed and implemented for short-range vehicular radar, designed to warn the driver of close-by overtaking vehicles (so-called 'blind-spot' warning). It employs a novel design of random

After discussing the nature of the electromagnetic field in urban environments, and the use of diversity techniques in fading media, the paper presents a survey of these techniques as applied to mobile radio, with emphasis on systems designed for ana

Diversity reception techniques can help to combat fast fading in urban areas, and this paper describes some predetection combining systems designed to be compatible with existing standard receivers. Quantitative results show that a worthwhile improve

A self-phasing aerial array using an amplitude-perturbing technique is described, and a method of obtaining the necessary control information is given. The system is intended for use in f.m. mobile radio links, and has the advantage of using an almos
