Downlink and uplink MIMO-SCMA System

Статья в сборнике трудов конференции

Sparse code multiple access is a promising multiple access technology capable of increasing the spectral efficiency of communication systems. Another technology that can improve the spectral or power efficiency is multiple input multiple output. Combining both technologies offers an advantage over classic approaches. This paper presents downlink and uplink multiple input multiple output sparse code multiple access with spatial diversity to improve performance of classic systems. It considers full rate full diversity of space-time block codes. We propose maximum likelihood multiple input multiple output detection scheme without using message passing algorithm for scenario with 2 and 4 transmitting and one receiving antenna. We also propose maximum ratio combining message passing algorithm detector for uplink model with multiple receiving antenna. Numerical results demonstrate better bit error rate performance compared to classic approaches.
