Interference bounds in power controlled systems

Capacity in a code-division multiple access (CDMA) system is often referred to in terms of the maximum number of users that can be supported within a carrier to interference ratio above a specified quality threshold. This pap er presents a simple analysis showing that the total mean interference in t he reverse channel, in a multi-tier scenario of a CDMA system with power co ntrol, is finite regardless of the number of surrounding tiers. Riemann-Hur witz analysis is introduced in order to obtain upper and lower interference bounds.
