In this paper, we derive analytically the per-user packet outage probability and the total system goodput for multiaccess systems using multiuser detector with adaptive successive interference cancellation (MUD-SIC). We consider a multiuser wireless system with n mobile users and a base station. We assume slow fading channels where packet transmission error (outage) is the primary concern even if strong channel coding is applied. To capture the effect of potential packet error, we consider the average packet error probability and the total system goodput, which measures the average b/s/Hz successfully delivered to the base station, of the n users. Unlike previous works, our analysis focus on the error-propagation effects in MUD-SIC detector where the packet outage event for the i-th decoded user is coupled with that in the i - 1,.., 1-th decoding attempts. We shall derive the optimal SIC decoding order (to maximize system goodput) and evaluate the closed-form per-user packet outage probabilities for the n users for MUD-SIC. Simulation results are used to verify the analytical expressions.
