Summary on Grant Application Form
Modern communication and broadcast systems put heavy demands on the radio spectrum. Radio channels must be re-used wherever possible, while at the same time avoiding unwanted interference. Good frequency planning algorithms control the interplay between spectral and geographical separations. The research programme proposed here will concentrate on systems built around cellular layouts, which are very familiar to engineers. Methods from discrete and combinatorial mathematics will be used to develop new and flexible frequency planning algorithms. These are urgently needed if the best performance is to be extracted from limited spectral resources. The likely benefits are new and efficient software tools for spectrum managers and system designers, together with enhanced understanding of alternative mathematical approaches to problems in radio channel assignment.
