Abstract
Mobile communication has become popular over the last couple of
decades. The channel between the base station and the mobile device depends of
the enviroment in which the mobile device is placed. The time of arrival
statistics of the signal arriving from the base station to the mobile device
depends on the channel. The time of arrival statistics is an important parameter
as it assists in determining the maximum width of the pulse that should be
transmitted over the channel. Geometrical channel model is one of the widely
used channel modeling techniques for determining the time of arrival statistics
of the signals. In this paper we approximate the gaussian distribution of
statterers around the mobile device by concentric annular rings of uniformly
distributed scatterers to evaluate the time of arival statistics. We subsequently
compare the satistics obtained by both the methods for validation of the results.
