Abstract This paper presents a geometrically based channel model for mobile‐communication systems. The model assumes that scatterers are uniformly distributed around the base station inside a circle with radius R that is determined by the coverage area of the base station. The probability density functions (pdfs) for the angle of arrival (AOA) and time of arrival (TOA) are derived for both omnidirectional and directional transmitting antenna systems. Important parameters for the multipath channel, such as angle spread, delay spread, and Doppler spectrum, are provided. © 2005 Wiley Periodicals, Inc.
