Multipath propagation measurements and their analyses are described. The work was carried out by the BBC over the period 1988 - 1990 as a contribution to the Eureka 147 Project, with the aim of providing statistical data required in the configuration of a Digital Audio Broadcast system.
Two different areas were chosen for the tests, one considered as representative of a generally built-up area with varying degrees of urbanisation, the other on the fringe of a relatively hilly area. In the first area two widely separated frequencies in the UHF band were used to enable estimates to be made of frequency dependence.
The results are compared with those of other similar measurement programmes in both Europe and the USA available prior to 1991. In general a somewhat lower incidence of long-delay multipath was observed in the BBC results, especially in the case of the hilly area.
