Pattern Division Multiple Access (PDMA) is a novel non-orthogonal multiple access scheme proposed to meet the demand of massive connection in the future 5G communications. PDMA is based on the joint design of transmitter and receiver. The multiuser signals are superposed on the multiple signal domains based on different characteristic patterns at the transmitter side, and the successive interference cancellation (SIC) is used to separate the multiuser signals at the receiver side. In this paper, we proposed the enhanced technology of PDMA, named as interleaver-based PDMA (IPDMA). IPDMA scheme could distinguish different user based on different bit-level interleavers, different characteristic patterns, and different combinations of bit-level interleaver and characteristic pattern. Then the iterative decoding and detection was used at the receiver to separate multi-users. Simulation results showed that the proposed IPDMA could improve the block error rate (BLER) performance, compared to the PDMA. And analysis indicated that the complexity of the IPDMA scheme is closed to the PDMA scheme.
