Abstract	In this paper we have considered a new resourse sharing approach for wireless access which is based on power assignment strategy, where two sources transmit their information simultaneously to the destination with the different power but use the same sub-band (time-frewquency unit). It discusses the concept of non-orthogonal multiple access (NOMA) which has a power multiplexing at the transmitter side to improve the spectrum efficiency and a successive interference cancellation (SIC) at the receiver side. Multi-antenna techniques have been deeply studied during the past decade to boost system performance by virtue of spatial multiplexing and/or spatial diversity. It is proved that NOMA combined with MIMO techniques can achieve further system performance improvement. In this paper, the SIC structure is designed, and the MMSE-SICand ZF-SIC algorithm is simulated and the effects of different order is anlysised. The conclusion is that the MMSE-SIC algorithm based on SINR ordering has lower complexity and better performance and is more suitable for NOMA.
