Outage Performance of Relay Sparse Code Multiple Access Networks
2019 IEEE Wireless Communications and Networking Conference (WCNC), 2019This paper presents a downlink multi-user network model based on sparse code multiple access (SCMA), where two phases cooperative transmission strategy is introduced to reduce the average outage probability. Motivated by the fact that the reliability is an important indicator in the next generation mobile communication system.

Design of permutation-based sparse code multiple access system
2017 IEEE 28th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC), 2017We consider the problem of designing a sparse code multiple access (SCMA) codebook that is based on permutation. Conventional SCMA is a multidimensional codebook-based non-orthogonal spreading technique, in which each layer of incoming bits are directly mapped to multidimensional codewords which have nonzero entries on the same resources.
