Abstract

With the approaching of Internet of Things (IoT), non-orthogonal multiple access technology was proposed in the fifth generation (5G) mobile communication system to improve the system capacity and meet the needs of massive connectivity. Multi-User Shared Access (MUSA) technology is a non-orthogonal multiple access technology of code domain. MUSA receiver adopts multi-user detection algorithm, mainly using interference cancellation based on linear detection. This paper proposes the successive-parallel interference cancellation multi-user detection algorithm for the shortage of typical multi-user detection algorithms of MUSA uplink receiver, and gives the comparison results of the proposed algorithm and typical algorithms. Compared with parallel interference cancellation detection algorithm, the proposed algorithm improves the detection performance greatly. Compared with successive interference cancellation detection algorithm, the proposed algorithm reduces the processing time delay effectively.
