On the receiving power pattern for cellular CDMA systems employing successive interference cancellation

Abstract

When successive interference cancellation (SIC) is employed, the mobile users with high signal-to-interference-plus-noise ratio (SINR) do not necessarily produce excessive multiple access interference as they do when single user detection is employed. Thus, in cellular CDMA systems employing SIC, there exists an alternative receiving power pattern other than the geometric receiving power pattern, which can significantly reduce the average outage probability of the systems.
