Abstract :
We report on our analysis of the cumulative distribution of power received, fade duration (continuous interval during which communication becomes impossible) and non-fade duration (continuous interval during which communication is possible) while moving within a mid-size city, with different elevation angles for subsynchronous ETS-VI orbit and 47/spl deg/ elevation for ETS-V geostationary orbit, respectively. The measurement frequency for each angle was 2.1 GHz (S-band) and 1.5 GHz (L-band). These parameters of angles are considered to be ideal for the study of communication-path properties in satellite communications.
