In this paper we present a simulation tool for macro cell environment based on geometrical and statistical representation of the scatterers and on the COST 259 directional channel model (DCM). This tool uses gaussianly distributed scatterers for each cluster. This distribution is naturally more realistic than the uniform distribution leading to time-of-arrival (TOA) and angle of arrival (AOA) distributions closer to experimental results. This geometrically based model simulates the TOA dispersion present in wide band channel models and the AOA dispersion necessary for systems that explore spatial diversity. This tool also incorporates the concept of line-of-sight (LOS) and non-line-of-sight (NLOS) and its birth and death as the mobile station (MS) moves in a cell, as well as the appearance and disappearance of additional clusters of scatterers. The output provided by this simulation tool is comprised of all the complex amplitudes, delays and angles of arrival of all multipath components associated with each cluster of scatterers. Mean attenuation and slow fading effects are also incorporated to the model and fast fading appears as a consequence of the multipath interference.
