Abstract :
Delay profiles were measured at three microwave frequencies (3.35 GHz, 8.45 GHz, 15.75 GHz) in order to predict transmission performance of digital mobile communication systems. The transmission performance was efficiently obtained by computer using a stochastic method based on the characteristic function method. The results showed that the transmission performance fluctuated even in the close vicinity of the transmission antenna and that megabit-per-second transmission rates was feasible in an urban multipath environment
