    Sparse code multiple access (SCMA) is an attractive non-orthogonal multiple access scheme for wireless communications. Meanwhile, space-time block coding (STBC) can achieve high diversity gains in fading channels. This paper proposes an uplink SCMA-STBC with a space-time-based message-passing algorithm (ST-MPA). Moreover, precoding is employed in the proposed SCMA-STBC to reduce the complexity of the receiver. The BER lower bound is derived for the proposed system. Simulation results show that the system with precoding provides a better BER performance than the case without precoding.
