Instead of successive interference cancellation (SIC) for uplink non-orthogonal multiple access systems with fixed decoding order based on the statistical channel state information (CSI), we focus on decoding with the dynamic order according to the instantaneous CSI. After modeling the channel fluctuation of all the users with different transmit powers and different path losses, a dynamic SIC receiver is proposed based on the instantaneous received power of different users. The outage probability of the proposed system is theoretically analyzed and the closed-form expressions for a three-user system are derived. Simulations are performed to validate the accuracy of the theoretical results.
