WCDMA uplink capacity of high-altitude platforms (HAPs) macrocells with incorporated HSUPA service

Abstract

The multiservice (voice, data, and high-speed uplink packet access (HSUPA)) uplink capacity and the interference statistics of high-altitude platforms wideband code-division multiple access macrocell are studied. The free-space propagation loss model with a log-normal shadowing is used in the analysis. It is concluded that the voice and data service are significantly affected by HSUPA users and that the macrocell capacity decreases dramatically when one of these users gets connected to it in the case that they share the same frequency band. Also, it is concluded that the capacity decrement is highly sensitive to the location of the HSUPA users. When the HSUPA users did not share the same frequency band with the voice and traditional data users, macrocell capacity will be 3 HSUPA users with a processing gain of 8 or 5.3 HSUPA users with a processing gain of 16.
