Effect of positional instability of an aerial platform on its CDMA performance
Effect of positional instability of an aerial platform on its CDMA performance
The effect of the changes in the position and inclination of an aerial platform (AP) on the number of users per cell (M) in a code division multiple access (CDMA) cellular system is described. The AP at 21 km uses a multiple beam antenna system to create elliptical cells on the Earth's surface. Vertical errors in altitude of the AP of ±0.5 km cause M to decrease by 1 to 2%, while horizontal displacement errors of up to 0.3 km result in a decrease in M of approximately 1%. An inclination of 5º from the horizontal significantly impairs M by 38%.

Abstract
The effect of the changes in the position and inclination of an aerial platform (AP) on the number of users per cell (M) in a code division multiple access (CDMA) cellular system is described. The AP at 21 km uses a multiple beam antenna system to create elliptical cells on the Earth's surface. Vertical errors in altitude of the AP of ±0.5 km cause M to decrease by 1 to 2%, while horizontal displacement errors of up to 0.3 km result in a decrease in M of approximately 1%. An inclination of 5º from the horizontal significantly impairs M by 38%.
