Abstract :
This paper presents techniques for obtaining direction of arrival (DOA) information from both narrowband and wideband radio channel measurements, with the use of spatial diversity. The multipaths arriving at the receiver are presented in a photographic form, which may be directly compared with the surroundings. The use of wideband channel information allows time-gated measurements to be made of the impinging signals. This technique is ideally suited to the validation of radio cellular propagation tools
