This paper proposes a new multi-user detection scheme for sparse code multiple access (SCMA) system in grant-free scenario. SCMA systems use a message passing algorithm which considers all user equipments (UEs) to be active. However, in a practical system, UEs do not always request resources. A multi-user detection procedure enables the decoder to mitigate interference from proper active UEs and to ignore the signal from inactive UEs. Therefore, we propose a multi-user detection scheme for SCMA system. The simulation results present that the proposed SCMA receiver structure achieves a remarkable enhancement in false alarm probability, miss detection probability.
