Radio channel simulation for micro-cellular wireless personal communication systems

Radio channel models developed for traditional macro-cellular systems can not be used for micro- and pico-cellular environments of modern wireless personal communication systems (PCS). This is mainly because of distinct differences in propagation characteristics and much smaller outdoor and indoor micro-cell sizes [1]. It is therefore essential to develop site specific models [2], [3] for a realistic simulation of radio channel and its temporal and spectral characterizations.
