Abstract
This paper considers the interference in a cellular CDMA system as the sum of interference from within the cell and from outside the cell. The in-cell interference is relatively predictable and so attention is turned to obtaining statistics for the out-of-cell interference. It is shown that the interference due to an arbitrary distribution of mobiles for a general cellular system can be fairly quickly evaluated once a small number of specific probability distributions have been found. These distributions are included for the specific case of inverse fourth power law and log-normal fading with standard deviation of 8 dB. Further results are obtained for various fully loaded systems based on these results, and a comparison of the theoretical limits on spectral efficiency for different required levels of link availability is included.
